Took a big jar down to my local river and scooped some water, soil, and plants to make a closed ecosystem. About a month into having it I noticed these tiny shrimp like creatures swimming around pretty fast and had absolutely no clue what they were and couldn’t find anything online that I typed in. Fast forward 7 months today when I randomly stumbled across your video. Thank you for solving my 7 month mystery! Been driving me crazy XD

I just found some while fishing from snagged lake plants. I found a bunch of small green ones and two medium sized tanish orange ones.

been keeping them in a 55 gal for a year, I think I like them better than fish. shrimp are breeding in there too. they are great for cleaning algae off everything including plants and java moss. they don't bother the plants until they run out of other food.

Thanks for this, Bob! Excellent teaching from you, as usual.

Super informative, I didn't expect this to be as in depth and scientific as it was but I'm glad it is! Well done

Awesome video. I just ordered some scuds from Goliad Farms to start a colony!

Great video production Bob, very well done.

Thank you so much for this!! Found some little hitchhikers in the plant I just bought, and it looks like this is them! Thankfully, I still have them in their initial cup, and I think I'll try to start a culture. Very interesting and informative video :)

Fantastic video man. Very great info. Everything I was looking for. I accidentally cultured these guys years ago and loved them! My betta loved them even more. My girlfriend at the time put some treatment stuff in the tank without my knowledge and it killed off they hundreds of them that we had established. I’ve been trying off and on ever since with my new tanks without success and now I know why thanks to you. I’ve been trying to start them in a spare tank with little to no lighting. Problem solved. Going to head down to the local pond tomorrow and collect some to start a new culture with.

Excellent research. Thank you.

Great video. Everything I could possibly need to know about them, no waste of time.

I just found these guys in my aquarium. Thanks for the info!

Best video on them I've seen! Thank you sir:)

This is really interesting and informative. Thanks so much for this!!!

Thank you very much! Excellent video and very informative.

Great instructional video.

Great video Bob

I made an eco jar months ago from a lake in Florida, I have a single pond apple snail and a rams horn snail but I’ve and have been trying to figure out what the little critters are! Thank you so much.

Great video. Nice to see one of my favourites given some love:-)

Could you do a video on Kuhli Loaches? I love your style and depth on these videos. Straight to the facts, kept it simple but not afraid to use the proper terminology. Yes please..... lol

Good guide to scuds, unique pet for aquarium, good luck always, greeting from indonesian ( lola )

this was very helpful. i noticed something large swimming rapidly through my daphnia barrel a couple days ago. i couldn't imagine what it was, and first thought of fairy shrimp, which i have never seen, and had no idea we have freshwater shrimp too. i collected my daphnia from a temporary pool this spring, i live right outside of dc in maryland, and got a whole mix of interesting animals, like cyclops, and what i think are seed shrimp. i must have collected some eggs or nymphs of ''scuds'' as well. anyway, it was quite a surprise to see this, and today i saw it again and was able to net it. i could see it was some kind of tiny shrimp about 1/8 inch long. i want to culture these as well as the daphnia, and i hope more appear in time. i have a lot of bright green filamentous algae in the tank i put the specimen in, i think it will eat that. i also feed yeast to the daphnia, maybe it can eat that too. so thanks for this vid, most info on google is quite vague about culturing these animals.

Make more videos just like this! So informative and soothing.

I have scuds in my shrimp tank and I have over 600+ shrimps in a 20g tank that almost never gets water changes, all I really do is watch the TDS and when it starts to drop, I remineralize the water I put back in to about 250 TDS with the salt shrimp minerals for cherries. Given, I would prefer them not being in there.... They don't seem to be as big of a problem as people make it out to be. As long as you don't feed at night, they don't get as much access to the food in the tank people like to make it out to be.

I got some from the canal by mine . I really liked having them

Wow, I imagine intelligence agencies briefings for American presidents aren't this well put together. The way you credited the professors and the white papers was so surprising and impressive. This should be up for a Peabody Award just for it's excellence in form alone.

Cool video. Thanks for sharing

Man you guys in the states are lucky with these!!! I live in southern Thailand and have searched every store in the region... no one has heard or seen them... ive contacted commercial aquarium plant farms here also... one owner has seen the odd one or two... but says they disappear by themselves... the stores I've contacted in bangkok haven't seen or heard of them... I'll be doing a tour of chatuchak fish market in a few weeks... one of the largest aquarium fish trade markets in the world!!! If I can't find them there... I will start trying wild caught at different locations.... failing that I'm going to say they are so uncommon here in Thailand they are almost unheard of.. Pity!!! They would be an amazing live food to add to my fishroom.

Hello, and thank you for this thoroughly researched video. It took me back to my days working with and identifying amphipods. I wanted to say that I don't think you have Hyalella azteca. Hyalella has a couple of small spines on its back on a couple of the segments near the swimming legs, and your amphipods don't have that. I think it's more likely that they're a species of Gammarus other than Gammarus fasciatus. Even if H. azteca and G. fasciatus are the most common scuds in the freshwater hobby that doesn't necessarily mean that they're the only ones. If you can get some good pictures of your scuds and upload them to iNaturalist someone might be able to give you a definite identification. Keep enjoying your scuds! I'm about to set up my first tank in many years and I will probably seed it with scuds if I don't get some coming in on my plants.

I have pretty small tank with a water filtration device. The scuds (gammarus pulex) fail to reproduce (they seem to try) and slowly die off. I wonder what’s the problem? Too much ammonia? I should maybe change the water more often? I thought they would be less sensitive.

Correction: Amphipods are not related to shrimp. They are in the same class on the taxonomic tree, but a class isn’t necessarily closely related. Instead, they are much more related to the terrestrial bugs you find crawling around on your driveway called Armadillidiidae, often called roly-pollies, pill bugs, or potato bugs (although from what I understand, there are two completely different insects colloquially referred to as potato bugs). Note that I say bug and insect, but Armadillidiidae aren’t bugs/insects - they just look like them on land.

Do they eat fungus biofilm?

I gotta remark that the "land scud" name Talitrus Saltator is the most awesome and villainous sounding name ever!!

I live slightly close to the endangered amphipod, it would be cool to see some!

Hi, very interesting. I have black scuds living in my garden, are black ones common, I'm in Brighton United Kingdom? Thanks John.

Hi sir! Do you think i can found amphipods in Mangrove Areas?

Are these the sames one's people feed aquarium turtles with? In the feeding box says: "gammarus sp." and in other (older) one, "gammarus lacustris". I'd like to start a farming business oriented to pet food. Any tips (links) where to do research? P.S. - I'm in Europe. Thank you!

what’s interesting is that my scuds thrive in my canister filter, which is in darkness 24/7. they’ve sure got some adaptability

I tried having Gammarus pulex in my aquarium once, but minutes after I put them into the tank, they started standing still, and all died later that day. What could have caused this? I had crayfish and shrimp in there, and they were all in perfect condition. I wanna try having scuds again, but I don't know what to do with my aquarium water to make sure they'll be okay, I can't find anything about it online.

so how can I get an initial colony?

Are they small enough for guppies to eat?

a lesser known but highly common terrestrial amphipod is the lawn shrimp/lawn flea. These guys went full isopod with their terrestrial adaptations.

Hello , I wanna ask that does scuds cause any harm to humans , if we drink water from that source where scuds reside ??? Plz answer me

Do adult Medaka rice feed on scud?

Shoutout fromRVA

They are related to icopods

How can i catch them in the wild?

Crangonyx pseudogracilis (Northern River Shrimp) is more tolerant of low oxygen, high water temperatures and pollution than Gammarus spp. I find it a much better tank janitor

How to kill scuds in shrimp tank, sir?

Scuds are a cold water shrimp or crustacean s

Scuds LOVE duckweed.

These just showed up in my tank without me even trying. They are cute and seemingly good for the tank environment, but I would give them away for free because they are also annoying and never seem to stop breeding.

i have pet scuds in my ecosphere

OMG I HAVE SCUDSSS nooo

Canned green beans LMAO

Yeah they're great until you get a variety that eats all your weeping moss.

Cockroaches of the water.

Narrator needs work

Man I started seeing these all over my pront porch and 9nsude my guest house dried up. At first I thort they were fukn ticks dead from my dogs antiflea tick meds. After long research.... it turns out they are lawn shrimps, land cousins of these

awesome video; i just want to give a shout-out to the ultimate SCUD, a freshwater species that comes from Russia, same as the SCUD missiles of yesteryear. Acanthogammarus victorii. Look'm up. Amazing critters.

Hmm how can I attract these little guys into a trap 🪤 I’m not sure the dnr would like me digging through the mud on the shoreline
