Ghost/Glass shrimp questions.

I recently had an unconfirmed columnaris outbreak in my 20G long.

I lost my fry and a few juveniles.

My adult male guppy is fine.

tested my water today 0 ammonia, 0 nitrate, and around 5ppm nitrite.

I double tested to make sure I hadn't screwed up, and 3 people confirmed color coding for the test tubes.


The other day I had 5 healthy looking guppies, and I'm down to 2 now.

I saw a ghost shrimp tackle a juvenile guppy, at about 3/4's of an inch from the filter intake, and thought nothing of it.

That is until I found it's skeleton on the floor of my aquarium later that day, picked clean.

I figured these were omnivores, but I didn't think that they'd take anything larger than fry down.

The shrimp are about the size of my adult male guppy- finnage about an inch.

I like them, but would rather move them then have them eating my guppies!



Has anyone else had these ghost/Glass shrimp eat juvenile or adult fish the size of a guppy?

OMG I've never heard of ghost shrimp doing that. I have read that sometimes what the stores sell as ghost shrimp are actually another more aggressive type of shrimp. I forgot what they're called but they look pretty much the same as ghost shrimp. People have reported them going after their betta fish even, and those guys can be 2.5-3 inches long.
There are a variety of shrimps sold as"ghost" shrimp and often enough some of the more aggressive species will be scooped up and sold along with them. The more aggressive types can generally be id'd by their longer 'grabber' arms with very noticeable long pincers on the end. If you've got these, move 'em out. Though not definitive, they'll also tend to have more red bits than your average ghost.

That said, any and all shrimp will happily munch on a dead or dying fish and seeing a shrimp eating remains doesn't necessarily make the shrimp a villain, nor is the cause of death in a fish always obvious.
Thanks

best I can tell, these are transparent ghost/glass shrimp.

they don't seem to have larger claws.

2 out of the 9 are more of a whitish, but not death white.

And those two have longer, antennae I believe.

All seem to love the water flow, which is minimal unless my tank is filled to the rim.

The two that appear different from the rest may go in a larger tank, so they'd be less likely to go to the top where my guppies seem to congregate until week 3.

Thanks again for all the info, everyone.

So I confirmed it today, the larger antennae Shrimp have small red "flecking" on their tails.
One of them scuttled up the front of my tank and latched to a 1" guppy while trying to separate them, It had it's little arms in the guppies Gill slit.

The rest of the shrimp helped eat the body, as I couldn't separate them.

Those have got to be the more aggressive shrimp sold as ghost shrimp. They look very similar and when I saw them at Petco (the shrimp) they were not called ghost shrimp.

IME, I have never had a Ghost Shrimp attempt to attack a fish, even very small fish. My Amano's that I have now are much more aggresive than any Ghost Shrimp I've ever kept.

There are inaccuracies in identifying shrimp.

Sometimes prawns are mistakenly labelled ghost shrimp.

Your poor fish are not the first to be taken out by killer shrimp. That one will likely end up 3 inches long.
Confusion

Any ideas on how to process these buggers before bagging them at the LFS?

I'm thinking that I'll probably separate them into the larger tank.

The killer shrimp are about the same size as my adult male guppy, and about the same size as the other 9.


I definitely love the shrimp though, once I establish a guppy strain or two, I might try my hand at a full blown shrimp tank.


Thanks for the help everyone.
