I have a community tank with plenty of live plants, a pond snail infestation, and some very old fish. Today when changing the carbon in the filter, I noticed HUNDREDS of small shelled invertabrates with small antenae. They look like small white baby snails, but they move like demons.

What the heck are these?

They are most likely a type of copopod. The common name escapes me at the moment. Most a quite harmless. In fact, most will eagerly take them as food. That probably why you see them in the filter and not the main tank, the fish eat them as soon as see them.

It could mean you're over feeding, but I've seen them in tanks that haven't seen a single flake of food.

Hope this helps...

I'm probably wrong but they sound like trumpet snails. I've heard they clog filters but they're otherwise harmless. very tough little things. just scoop them out, it's hard for loaches to eat them. that is if they are trmpet snails.

I think you're right tolkeinfreak. There's no way that they are snails, they're seriously faster than any fish I've ever seen. Thanks for letting me know..I've never heard of them before.

Yeah, that sounds like a copopod. Here is a pic of one.

OK, I went to my LFS today and I got to see some copopods, and that's not what they are. My guys have shells (about 2 mm long), but they are waaaaay to fast to be snails. They might not have antennae...legs? I have no idea.

They live in the gravel and filter and come out at night. They also seem to swarm when food of some kind is around. Anybody had any experiance with something like this? I've stumped everyone I've spoken to.
