Amphipod of some sort, looks like Gammarus.

 

I'd like a bunch of those. Clean-up crew plus great fish treats.

Thanks for the ID! I think ypu are right.

This is a shrimp only tank. Will they hurt the shrimp? I have a couple that are berried, so I don't want to risk taking them out to get rid of the gammarus if i don't have to.

Also are the small white worms on the glass their larvae then and not planaria? Can't get a good picture of those.

Gammarus shouldn't bother shrimp. White worms on the glass could be harmless or planaria, hard to say without a photo. Planaria have triangle shaped heads, most flatworms do not.

 

It’s a daphnia



I recently had the same situation. Uggg. Use planeria zero and that will wipe out the planeria and hydra and other non desirables. I hate buying plants for that reason. If you don’t bleach them first, you will get hit hikers. The thing in the bowl looks like a daphnia to me. I got one of those too. Freaked me out since it did not move like a shrimp. It is a crustacean so planeria zero will not get rid of that. If you don’t like them....I don’t....you need to catch them....sigh

Hope this helps.

 

Far too large to be Daphnia, and wrong shape.

Daphnia:

Gammarus:

For what it's worth, most appropriately sized fish will make short work of either.

 

So what small fish can you add to a shrimp only tank to eat the detritus worms or other non desirables without eating your shrimp?

Bump:

Just saying....I don’t want to meet the guammus........every time I think I have seen it all...something else shows up. What’s up with that? Lol

 

It's a gammarus and No Planaria/Planaria Zero is not guaranteed to wipe out the "white worms" - if they are not planaria. If they are detritus worms or rhabdocoela flatworms, then the product might not do anything to them.

 

Possible fishes could include kuhli loaches *or* pygmy cories... might be others. Not guaranteed they *wont* eat shrimp, but many people do keep both species with shrimp and have thriving colonies.


Might be a bit odd but I kind of think gammarus are cute! lol They're like underwater roly polies! Never dealt with them myself though... but I've seen them!

 

Yes, I don't mind their looks so much, as I can barely make out the features. I just want my shrimp and potential baby shrimp to be safe! I've been just catching the big ones put whenever possible, until I can decide what to do about them. I'm setting up another 10 gallon, so I will hold off on fish until that is ready for them long term.

Regarding the white worms, I used panacur, but they did not go away, so at this point I think they are detritus worms. As far as I know, they don't harm shrimp.

Sidenote: This was my first post on the forum and everyone's help has been MUCH appreciated!

 

Gammarus/scuds, if they get large enough, can harm and eat shrimp - especially right after a molt or if they're juveniles with softer shells.

I've also had them catch Endler fry and eat them.

If you don't have any young fish or shrimp to worry about, they shouldn't be much of a concern.

 

Creatures

Since setting up my tank....about 6 weeks....and adding plants......various creatures have popped up. Is this normal? Or is it just an unfortunate reality that comes with live plants? And for shrimp breeding in particular......how do you keep detritus worms under control without starving your tank? It seems that powdered foods are best for new shrimplettes but I feel like providing food and handling worms are a battle.

 

Yes, it's normal. It's part of having a healthy (as healthy as humans can maintain) ecosystem in a glass box.

Detritus worms, daphnia explosions and all that are generally only going to be around in large numbers when your tank is young. Give it a couple months and their populations will balance out or disappear all together.

If you have a well-established tank (say, 6 months+)? Baby and juvenile shrimp will have all the food they need to survive. Shrimplet-specific foods are really only something to use if you know you need them or when you've been shrimping long enough to try something new. And even then, you're feeding such tiny amounts that foods usually don't create any issues.

I guess a good question might be... are the worms kind of short and fat/flat? And really small?

Or long and slender? And kind of... well... long?


Short, fat/flat and small points to rhabdocoela flatworms. Not always harmed by treatment to get rid of planaria.

Long, slender, and... once again, long... that could be detritus (swims like a snake if in water column), nematodes (squiggles...) or possibly some other worm.

 

I've only seen them on the glass, but they are maybe 1-2mm long max and sort of squiggly, like they crawl in an S shape. Not a lot of shape to them...but maybe they are pointed a bit at the ends?

 

Hi, I found another one of these things in my aquarium today and I think you are correct. Upon closer inspection, it looked like a Gammarus. Where do they come from? How did it get in my aquarium and how do you get rid of them? Are they harmful? I’m so grossed out.
