I noticed about 5 or so organisms if you will in my tank this morning. 55 gallon FOWLR, parameters in check. I have two clowns with a variety of 10 snails. They are not even a centimeter in diameter and three were on my glass and i noticed two more swimming near the surface. Their swimming patter was to sink about an inch and then that would like flap their arms/legs and pop back to the surface similar to an octopus. They have 8 legs and at the end of each leg their was a clear long arm. I tried to get a picture but they are too small. I luckily clicked randomly into another thread on here and someone mentioned they have hydroid jellyfish outbreak? I googled it and that looks very similar to what I was seeing. Anyone have advice on what this is and if I should do anything about them?

Thanks

If they are indeed hydroid jellyfish, they usually run their course given time. No worries.

Snail eggs.

Hydroid larvae( look like tiny jelly fish) are not harmful to most organisms. They can sting but are too small to be a worry . They are deadly to some fish fry, particularly seahorses,however. Generally they will disappear and do no harm.

I agree the picture is a nice cluster of cerith snail eggs.
