I have the zebra & the Leopard danio's in a 75 gal aquarium & 6 albino Cories, I also have 9 commit goldfish in a 110 gal stock tank indoors for the winter mons of Indiana. I love all my fish they keep me busy doing things for them.

Is it necessary to listen this annoying sounds in background if I want to have the fish without heater ? 🙉🎧

So true, you're right ❤.

I tried 70° they all died then bought 40 more, yep I'm rich boy sellin Crack, put at 77° they all triple in size in 3 weeks. Where you at boy

Hey, hows the tank going bro? Upload a video to see :D

Thank you for your comment. Yes here in the states everyone wants to go for tropical fish, but there are plenty of fish in the hobby that do well without a heater at room temperature. Guppies are fun. They have tons of babies 😅

Hi Sean. You totally can do fine without heaters with the right fish, the stable room temperature, and a mild climate. It's actually better for planted tanks because you will have less algae growth.

I had a pleco in there as well for algae as bit of back up but he was like the Tank boss as he got bigger than my hand ✋ lol

When I put my pleco in he just disappeared for over a year and I fort he had Died as I didn't see him but what he had done was Sucked a Hole out of this log and used it to hide his body in and one night I just saw this big Shadow swim round my tank 😬 and realized it was the pleco lol 😆 as he had been hiding for over a year in my 50 liter tank as it was a natural self cleaning tank and I only needed to clean it properly every year as it mostly cleaned it's self

Thank you 😊

Glad you enjoyed it

Yes, goldfish are great if you set up the tank correctly. They actually aren't really beginner fish given how large they get and how hard they are on a biological filtration system. They are very tolerant of coldwater.

They are great fish - just don’t keep them around plants as they will eat most of them

Hi Shanny. I agree that most fish actually do not need heaters. I recall GreenAqua talking about it during an aquascaping video of theirs that aquarium water will stay at 1-2 degrees higher than room temperature so they only keep fish and plants that can live in room temperature waters. If you live in a cold climate though, you likely will need a heater as temperatures will drop throughout the come. The issue is usually cooling in water climates or during the summer.

your advice is extreamly dependant on your location, I accidentally turned off the wrong multiplug which included the fishtank heaters and about 80% of my fish died. at my location, it gets to about 8 degrees inside without heating

Hi George. They wouldn’t be able to survive a cold winter. I would bring them indoors.

Those are longfin Zebra Danios. You can find them at local fish stores

@@AquariumStoreDepot now I'm going to have to look for them

White cloud minnows and Japanese rice fish would both be suitable.

Techically all these fish except for goldfish can do well in a naturally heavily planted tank with no filter if done right. The smaller the fish the better the chance though. Minnows and rice fish would be the best candidates on this list for a Coldwater natural tank.

Coldwater in the aquarium world is anything that can live without a heater in a room temperature environment (68-72 degrees). Ponds are a different matter

I’m sorry to hear that. What part of the live do you in live in?

@@AquariumStoreDepot Uttar Pradesh.. Dubagga

That's fair. I can do a Coldwater vs. Coolwater fish video. This video was focused on fish that would live without a heater in room temperature in most neutral climates. The coldwater would be those who can tolerate temps lower than 65F. This would include some frost hardy fish like goldfish and koi. I have some backlog in my content schedule, but I can add it to the project hopper :).

Just about any fish native to the United States would do well in temperatures 15 to 20C, but you would need to do your research, including what species are banned in the U.K. Almost all of these fish could survive an English winter and cause ecological damage. To see their colors really pop, just raise the temperature a couple of degrees. The various species of shiners would be similar to barbs. Red shiners are quite popular in Europe, and I think they are very beautiful. Europeans have a different name for red shiners--rainbow something-or-other. Golden shiners are beautiful, but they would be unreasonably large for most aquarists--8 inches or so--and they'd need to be in a group. The fathead minnow and its color variant, the rosy red minnow, are similar to the shiners. Rosy reds are often sold here in the Unites States as feeder fish. All the minnows and shiners need to be kept in groups just like barbs. We have killifishes, but I really don't know anything about them. You'd need to do your research. Killifishes are short-lived, so many enthusiasts breed them so they won't run out. There are also mosquito fish. They are live-bearers, and they look similar to wild type guppies. They're a little bit larger than guppies. But they won't do well with other species; they're terrible fin-nippers. If I were keeping mosquito fish (and I have), I'd make sure to have enough of them in the tank to spread out the aggression. Your tank will always be active, even with just the room light on. They'll like a large enough open space to chase each other in, but they'll appreciate a planted area to retreat to when they get tired or bullied. Successful breeding in an aquarium can be a little tricky as they actively search out the fry to eat. I love these fish. Our sunfish would be similar in size and personality to medium to largish cichlids. They are centrarchids, the same family as the black basses. (The pygmy sunfishes are a different family.) Most sunfish species are very scrappy. The bluegills are the gentle giants of the sunfish, but they could reach 10 to 12 inches, and "gentle" means "gentle for a sunfish." The longear and northern sunfishes are the most beautiful in my opinion, but like most sunfishes, they are rough customers, both among themselves and with other species. And when two sunfish pair off to mate, all bets are off. Unlike cichlids, the male centrarchid acts as a single-father protecting his children, and the female is going to have to move out. I think, but I'm not sure, that pumpkin seed sunfish are popular in Europe. The species to watch out for is the green sunfish, as they are the most pugnacious. I'm not sure I'd trust more than one green sunfish, by itself, in a 200 to 250ltr aquarium. Oh, and centrarchids are a commitment, living 8 to 10 years or maybe longer with proper care. But if you get tired of them, you can fry them and eat them. I'd suggest the various species of darters as well. Darters live on the bottom because they don't have a swim bladder, and they are completely peaceful. You'd have to feed them food that would sink to the bottom. But they do require setting up a current as most of them come from flowing streams. I hope this helps.

@@construct3 Thanks!

Yes I understand. In the hobby - the term is typically used for fish that can live in room temperature or lower water.

Yes tetras are the best schooling fish for freshwater aquariums

That's been my experience as well, I have them with my white cloud minnows and paradise fish unheated in the UK

🎉

Yes, Guppies prefer a temperature range of 72 to 82 degrees Fahrenheit (22-28 C).

@@AquariumStoreDepot So why give a temperature range of 63-82 on the video?

I’ve had guppies at both 63-65 and 70-75 and they both do great!

The definition of cold water fish in the hobby are fish that do fine in room temperature water

It can be too cold for some fish. Coldwater is defined in the hobby as fish that do fine in room temperature water or below

​@@AquariumStoreDepot what about the fish that grow in the lakes and rivers of colder climates - seasonally anywhere form 2-18C? By the way I'm not suggesting they should be kept at 2C, I'm just wondering what you would call them? Electricity is very expensive so I want to keep a tank without a heater.

@@TheMAU5SoundsLikThis for that I would defer to koi and goldfish. They are going to be the most cold weather resistant of ornamental fish. Japanese Rice Fish and minnows could work too

​@@TheMAU5SoundsLikThiswhy not set up a tank, at least filled with water, in the area of room, and put a thermometer in the tank. That way you can see what your unheated tank temperature would be. I'm in Scotland, in a cold flat, I keep my windows open all the time, yet my tank water is normally around twenty Celsius. I have danio, platy, rainbow shiner, mountain minnow and Cory in the tank. I got another two tanks, which I'll probably do tropical, fighting fish in one, and raspora and tetra, or guppy, in the other. Or get more tanks lol. I believe cold water encourages danio to breed, it's like when the rains come bringing colder water. I've got a couple of babies, I believe they are platy, which I'm trying to grow up in a separate tank. But if your natural tank is around low twenties, you would only need another few degrees for tropical, so shouldn't be too expensive

Florida flag fish are another great cool/cold water fish, and absolutely decimate hair algae, they are semi-aggressive to aggressive depending on tank mates and if they’re breeding I have a trio in a 20 Long that I use as my algae destroyer tank, these little 2” long fish even bully the 4”’long crawfish out of her burrow (the crawfish is extremely laid back and won’t even eat guppies…)

Goldfish are extremely tolerant and really can adapt to anything. While they can live fine - I try to steer ppl to general best practices. One of the longest goldfish ever recorded lived in a 29 gallon tank for many years

If you live in the southern hemisphere yeah, otherwise tropical fish need warm water.

They even benefit from it

It’s about consistency

Why do you assume everyone's home is heated to nearly 80°F?

@@PULAG all depends on what fish you keep some fish prefer lower temperature

Guppies are perfectly fine in an unheated tank as long as the temperature does not go below 15°c they can adapt to subtropical conditions

They’ll be fine in unheated tanks

Most fish don’t need a heater because house temperature

That really depends on genetics a lot. More wild varieties will have different tolerance to cold than lines kept for many generations in cooler conditions.

Wingei (endlers) do better than reticulata in lower temps
