Also could be a very small dragonfly naiad--funny that it would be in your tank, because most aquatic insects cannot complete their life cycles in aquariums.

It could have come with plants if they were grown out-of-doors.

It is probably nothing to worry about. Most aquatic insects will be harmless in aquairums, except for large dragonfly naiads, which can eat fish.

I found it in the red cherry shrimp tank, it was like 5 times bigger that the shrimplets, so removed it and put it in the other neon tetra tank

The original post is a stonefly nymph. The damselfly nymph has 3 FEATHER shaped gills on the end of it's abdomen. The stonefly has 2 antennae.

When it swims, does it wiggle back and forth and slowly sink? Damselfly nymphs don't use their legs to swim. All of them in the great white north don't, anyways...


There are some other deadly aquatic larva besides dragonfly nymphs... Water beetle larva, backswimmers and giant water bugs all catch and eat small fish. They would be interesting subjects for a small aquarium, I would think. I kept a beetle larva for a few months, but it died because it couldn't pupate.

My tank sucks now

Better keep a close count on your fish...

I'd kill it, personally. They're predatory, so it's just a matter of how big it will get and whether or not it can tackle a fully grown tetra.

Ooh that worm is weird. Aren't bloodworms just mosquito larvae? All the ones I have purchased by that name were. I've never seen a mosquito larva that big.

It looks like it has a mouth at the end.

mistergreen, that drawing appears to be a tapeworm. I don't think it's a tapeworm, it doesn't look like one and I've never seen one living outside an animal's intestine. As to what it actually is...no idea.
