I don't know about bryozoans but the hydras are really cool in my opinion. I've never heard that there was anything harmful about hydras and even my stepmother, who is a marine biologist, spoke about them in a way that indicated that they won't hurt anything in your fresh water tank.

frokm what i read they are carnivirous.....eating anything that they can catch. mind you anything small enough would be either, fry or the brine shrimp that i feed. i mean i dunno i dont really have a problem with them but i am just wondering where they might have come from.

Yup! New Radioshack delux model. I haven't seen a hydra in a while in my tanks. I think my fish or snails ate them.

Hydras can usually harm fish under one inch and definitely kill fry. They also have no determined life cycle i.e. they will live as long as they have food and are not eaten. I have seen snails eating them in a friend's tank its note worthy though that the same snail eating them had one on his shell lol cant get that one. Eventually the hydra population in his tank died off maybe from the snails and maybe from lack of food.

They've never hurt any of my fish. I don't think they're parasites. They catch small bugs like an anemonieie does I believe.

No they are not parasites but some can hurt you fish. Their stings are like a jellyfish some larger hydra's stings will be harmful to your fish if they are small like dario or neons.
