I don't know how it looks in real life but the before-state of the blackwater tank looks amazing on camera imo. Wouldn't call it a failed tank, just a less preferred one.

MD, I've run a filter with carbon on tanks where the wood leeches lots of tanins. The carbon removes the tannins and you don't have to waste so much water.

Now THAT'S a black water aquarium HAHA

This black water tank is looking fabulous now. Yes, those look to be the rainbow babies, the roots of the floating may have done the job of the spawning mop, lucky you MD❤ Waiting for timmy’s another new home. Dude has had more homes than me😅

I absolutely love Blackwater Aquariums! A perfect display to see natural behavior of your fish!

I think I like blackwater much darker then you do. Though the state of the beginning was only a TAD too dark for me. A suggestion: underwater spot lighting. Tanner from Serpa Design did some underwater moody lighting in his massive 350 gallon jungle palidarium. It made the water have spaces where you can see and appreciate the depth of the scape, but also darker pockets for shy fish to hide in the shadows

Rainbows normally breed on spawning mops and long roots of floating plants, so those are almost definitely rainbows. Always exciting when your fish breed on accident.

They are 100% rainbowfish, size says between 2-3 months old. Rainbowfish are egg scattering fish and they may have laid eggs on the floating plants you used in the owl tank. The fry are miniscule, so tiny that they can't even fit a baby brine shrimp in their mouth so you obviously had enough green water organisms for a couple to survive with no other predators in the tank.

I think blackwater is the kind of tank you really have to wait on for that tint to be right. Overtime it really does leach less and less. But this really is what is best for fish and is really replicates natural look. The tanins don't block any of the light for the plants that they need, just makes it seem darker but the wavelenghts the plants need are not affected

Black Molly fish babies tend to stay near the surface of the water, which unfortunately makes them vulnerable to being hunted. On the other hand, Swordtail fish babies tend to stay closer to the bottom of the tank, providing them with some protection. In my experience, whenever I notice Black Molly fish babies in my tanks, I promptly transfer them to a separate tank to ensure their safety. By doing so, I can provide them with a more secure environment where they can grow and thrive without the risk of predation.

For Timmy’s tank when you are siliconing the eco earth stuff on the background I recommend throwing some eco bark and sphagnum moss in the mix. It’ll give a little more variation and realistic look to the background. I used to do this with my custom made tanks and it really made a difference

Man I love that blackwater tank. It’s a masterpiece. And just look at those cardinals, so vibrant and healthy, a setup like this is exactly what they need to thrive. Just don’t let the plants take over too much! The lightly planted look is what makes this tank and really accentuates the beautiful and rugged hardscape. Well done mate!!

Beautiful tanks! I can't wait for Timmy's tank 😃

I have been watching this channel for a few years now. Finally decided to go ahead and try my hand with a tank. Just finished setting up a blackwater setup with black neon tetras. Thanks for the inspiration.

Love the sword tail and mollie tank. Those sword tails are so vibrant they are practically glowing. Beautiful

Tank updates are super helpful for long term fish keeping. It helps to know how to keep it good and what to watch out for. It also helps to show the outgrowth so we can see what it looks like mature

Great video! Nice job on the hack-back MD ❤ and yes, the rainbow babies 😍 rainbows only spawn for a few hours in the early morning, theyre egg scatterers, usually on the roots of floating plants or those growing close to the surface. The eggs can take up to 10 days to hatch and the babies are tiny...theyre also incredibly slow growing, you wont be able to determine what kind of rainbow they are until theyre much older and start developing colours ❤ this update has made me happy 😁

I love seeing Timmy, I can remember when he was about the size of your fingernail. ❤ Looking forward to seeing him in his new tank. I hope you don’t have to pull the Blackwater tank down because I love the scape

Absolutely love the look of that blackwater tank. The fish looked so comfortable in there, though I do understand the need to enjoy the look. Well done on the rainbowfish fry, it is always nice to see fry especailly if from egg layers as they're harder to raise if not using micro live feeds. They are certainly rainbowfish as have bred thousands and know the look from a mile away. They will certainly be hybrids which is normally frowned upon in the rainbowfish community. This is due to chances of them getting into the aquarium hobby and messing up true strains due to their mixed genetics of different Rainbowfish Families, whether that be Melanotaenia, Chilatherina or Glossolepsis etc. depending on which ones are the parents. These hybrids don't normally bring anything special to the hobby of the many beautiful strains of rainbowfish already available in the hobby. Hybrids also tend to have a more aggressive temperament than true strains. Please make sure to always keep these separate if they survive.

Definitely some of my favourite fish in the blackwater tank!

That's pretty rad to see the 2 unexpected rainbow fry turn up in the shrimp tank. MD's been mentioning it in the last few videos, and I'd be pretty excited if that happened to me!

This doesn't look bad, just very natural. The fish probably like it.

That tank is far from failed. Needs some maintenance but far from a fail.

I absolutely love the way you said “now I wanted a Blackwater tank but this is ridiculous”. I also love the way you dealt with it. Thank you once again for showing us. You are a great inspiration.

Those are definitely baby bosemani rainbows, congratulations on the growing family!🥂🎉 I've bred preacox, turquoise and bosemani rainbows and they hold such a special place in my heart❤️

Aren't spawning mops often used to breed rainbows? Maybe those floating plant roots act as spawning mops and eggs attached to the roots transferred over. Just a thought. I do like that black-water tank. I'd say patience. MTC 🙂

Yup, looks like a rainbowfish baby. My guess is that the rainbows laid eggs (they have sticky eggs) on the roots of the floating plants and eventually hatched out your owls tank when you transferred the plants. Very cool :)

Oh my.. Really do appreciate you showing us your successes as well your ooopsies. When we are able to learn from the mistakes of others we don’t have to make them ourselves 😊

Yes MD those are 100% baby Rainbowfish! Will be interesting which kind they will be! Because you’ve got a big mix so could be anything. But just keep feeding them and you’ll be fine. They are slow growing tho so keep that in mind!

Wow that Molly and swordtail tank is stunning, what a beautiful combination of fish!

I didn't know you could put coffee in a fish tank. 🤣🤣🤣

Oh man the crypt pink flamingo is looking just stunning in the "plant garden" tank 🤩

I always know when I watch a MD Fish Tanks video I'm in a for a good time

Awesome update man. My home aquarium is a 4ft'er with some Malaysian Mangrove Root in it. Now, it's not leeching as badly as your wood, but I totally had a similar moment when I left it for a while. It's calming down now thankfully! Hopefully yours does too as it's a gorgeous tank.

Those rainbow fish are stunners

Just started my first Aquascape because of your channel, and because of you, I had enough hardscape material. I'm really happy with the results and it restarted a hobby for me. Thank you :)

when the water is darker, the more the neon shine, i like it

you will need to soak the coco coir (brick) for Timmys tank, coco coir is very absorbent and if you stick it on in its dehydrated state it will expand on the background and fall off in large amounts into the water possibly damaging the entire scape on the wall

I was just watching F ather Fish in the USA. He refered to you as a technican of natural fish tanks . Oneof the best , says you really understand a natural system . He also showed your studio , and said al, your tanks were awesome . Other people were mentioned . I mention this because i am happy i am following ohe of the best , before i set up my fish tank . Thank you.

Guys. When you're re-charging your purigen put it in a mason jar and stir or shake it lightly every few hours. That way you can get it to almost white again plus the chlorine doesn't evaporate. Mason jars FTW. Then... use activated carbon next to the purigen to make it all a lot more efficient.

Love the tank, definitely not a fail! Over time it may clear a bit with more water changes.

Keep up the hard work MD! ❤

Amazing to see how quickly your channel has grown since I started watching 4 years ago. Well done Squire!

I love the dark tanin look, looks very exotic and natural

you can put activecoal in the filter, from my experience its quite effective in removing the coloration from the tannins.

Lovely ❤ glad timmy's doing great 😂🎉

This was the best situation similarity I have ever seen so thank you for sharing your experience because I experienced exactly the same thing. I am dealing with exactly the same way you have.

Black water tank looks amazing, I’d love to try that one day. Seems like the fish just love it. Very cool

Hey my friend giving a shout-out from the other side of the pond Philadelphia region, I love watching your shows the flowers the fish everything. You have awakened my mind the real way and making an aquarium. I have plans to drain my tank and rebuild it the way I see you do it not just straight fish gravel. So keep on making them I'll be watching them and keep taking the tips that you put out there. Look forward to show you what you have inspired me to build

Love how you show us everything! I am learning! 💖

Great update video! Satisfied my MD Fishtanks craving!

That mollies tank is ridiculously awesome! Just perfect!

Ahhhh if only all filters was so easy to clean. The black water looks really good when your close to it but from a few ft away looks terrible

I love your videos MD! First time commenting but I've been watching for months now! Geueinly get so excited whenever you post.

Great video, always love some updates. Can't wait to see the you and Matt video, those are always so much fun!

everything looks stunning

Mollies fry like to hide out in plants at the top of the water. They'll stay there until they feel comfortable to move around. So, if you want the molly fry to survive, they need lots of plants at the top.

I love all the tanks! Thanks MD.

Loving the little update videos, vlog style vids are a good in between from the build videos!

This post was another very welcome and enjoyable morning discovery!

My CPD's are not the least bit shy, they swim around everywhere and even comes to the front of the tank to greet me (hoping to fed) along with the endler males they share the tank with whenever I pass by.

Can't wait to see timmy's tanks❤keep up the great work MD

Amazing aquascapes they all look great

Wow! That's tanning city mate? I absolutely love all the tanks that you featured in this video. Thanks for sharing 😊

I love the way the Swordtail and Mollies tank looks.

So much more informative than every successful tank proving small things can wreak having unknowingly being positive, or at least as far as I have watched for a change

The black water tank was really black ⚫. It looks much better now. Love all your tanks. 🐟🐠🐟🐠 Gina Hetlage

Some thoughts of a chemist on leaching out the tannins: Factors to consider: * Diffusion: If you have a differing concentration of tannins in your wood and water, the tannins (which are water soluble) will leach into the water until a concentration equilibrium of 50% wood/water is reached. * Max. Solubility: Every compound has a max. solubility. This means that you might not reach the theoretical concentration of 50% total tannins in the first "extraction" process. Due to a too high amount of them in the wood. So what do you need to do: 1. Change water --> Give enough time to extract max. 50% of tannins. This will probably first be regulated by solubility so actually be below 50% --> Repeat until the max. solubility is not reached anymore. 2. Now every extraction step will give you max. of 50% of the remaining tannins in the wood. The concentration will now decrease exponentially with every water change. Lets imagine you could actually solve 50% of the tannins in the water per water change: 50% (remaining tannins in wood) 25% 12,5% 6,25% 3,125% 1,5% ... (=exponential decrease) This shows us you need at least 5-6 (100%) water changes, if you want to remove 99% of leachable tannins in the wood. In reality this number will probably be higher because your first few water changes will be limited by solubility of tannins and no one changes 100% of water. So one of the main takeaways is: You can not just wait longer for more extraction to happen. Yes, extraction needs some time but when max. 50% of tannins/or soluble amount is reached more time will not help. It is much more effective to perform earlier water changes (once you see the color change) than to wait for days. The higher the concentration difference from wood/water the faster the extraction will work. Of course you could additionally take out the tannins of the water by using a matrix with high affinity to tannins (e.g. Purigen by Seachem) . Depending on how much tannins the matrix can store this will reduce the amount of water changes you will have to do. Hope this helps :)

very nice! looking forward to next build!

I have to say, I just loved the way it was before… still loving it after the water change. But if my Op matter to anybody, not only the fish are less shy and doing great, maybe even better than the other in your tanks, but the display of rocks with shadings, contrasts and hue of that tank makes it, for me one of the most Naturalistic Tanks I ever have seen in your gallery. Till now this is my absolute Favorite Tank.

I love my black water tank! I’m actually getting ready to replace the wood because I had to do a big water change and it took out a lot of the color and the wood isn’t leaking anymore out

I love that molly/sword tail tank its beautiful

Se ve bonito, es para amazónicos con hoja seca de almendro, es un tono diferente muy agradable, saludos de México Playa del Carmen 👍

Looks like “Tea Time” at MD’s studio. 😀

This just recently happened to me as well. I pulled some Cabomba Caroliniana out of my rainbow tank and floated it in another. Went in a week long vacation and came back with 4 fry swimming around with my guppies. Now at first I thought I had baby guppies but nope!! They are rainbows. Lol awesome man! Hey idea for you. I just recently scaped a bow front 35gal tank. I suggest trying one out. The bow magnifies the areas of the tank. So I have one piece of drift wood that looks closer than it really is and one that looks farther. It also magnified the size of them. It looks absolutely stunning. With your skill set I can see you having great success with aquascaping a bow front tank!!

Best aquarium channel on KZfaq by freaking mile

I said I only watch your channel occasionally but I did subscribe to it with notifications the very first time I saw it so keep up the good work 👍🏻.

Probably unhatched eggs were in floating plants..as they tend to lay eggs on string mops..floating plants roots system is an excellent natural base for them to lay eggs.

I had a similar challenge. I added purigen to my filter. It took three cycles before it lightened up enough.

the after is soooooo good!

MD please please keep up with the weekly updates on the new Ecosystem Aquarium😊

Those orange swords look great!

It was quite enjoyable dark red,even better when you redid the water

About 2 months ago I set up a 23 gallon shrimp/ Endler tank using the pond compost/ aquasoil and topping with sand. Let just say I already have a dwarf sag carpet! And about 20 more endlers and 40 more shrimp 😄

Best aquarium content on the web. You will have millions of subscribers when others discover your talents. Good for you, MD. Yo

Love watching your videos

I really like those updates :)

Rainbows lay their eggs on roots in the water. The plant roots likely had a few eggs on them and when you moved them they hatched out in the other tank. You actually hang a 'mop' in the water to breed rainbows (basically a lot of woolen strings hanging in a clump from some Styrofoam to simulate roots in the water)

Holy shit MD - Just noticed your subscriber count!!! You've come a long way from the shed!!! ❤❤❤

Cardinals look insane ❤

Got a tank sitting with just plants and snails about a month now, then out of no where I’ve got 2 fish fry identical to yours! Plants I got from the fish shop is a huge tank with fish, so must have been eggs attached

What a same it looked so good!

Hey! I had the same darn thing. Seachem makes a product called Purigen. I didn’t think it would work, but I’m about 25 hours most if not all of the tannin was gone. No harm was done! Just thought I’d share 😊

I made a new tank and transfers some plants and found 3 ranibow fry in my own tank too, lol. Keep an eye on their fins. It's a big tell. If they get the longer top/bottom fins they're definitely rainbows.

Am I to say added too many Protea cones but I don’t want to take them out so I’m just going to keep changing the water. Protea is a common plant species in Australia 🇦🇺 where I live. Thank goodness you made this video because I have my favourite channels but I only see your stuff occasionally. This was my favourite video ever that you have ever done. Now I know I’m not the only one going through it.

I had the same thing happen with my dwarf rainbows. Took some plants out and babies appeared. I am pretty sure that the plants I transplanted had eggs on them cause the babies were extremely small. It was summer time so I fed them with green water I just happened to have outside. Kept those babies for years. I only have one left now. A female, maybe 5 years or older. Old age catches up to us all.

Your aquarium looked perfect pre water change

Im so happy about Rainbow fish news ! That means the tank is on peak! Now that's what the blackwater tank looks like 😂. Timmy's new home coming ! Huge love and respect from India brother

I've found over the years that Molly fry are mostly herbivorous. I mainly keep Mollies just to help combat hair algae.
