any of you with planted tanks ever have problems with these things. i noticed i have them all over one of my anubus plants.....the look like little tiny sea anemones i red an article that said they are normally found in places where there are large amounts of live food present, now i have just recently started feeding my fish live brine shrimp but i just started last week
Also i noticed moss animals or bryozoans growing on my drift wood...don know what causes these
or how to get rid of either of them anyone have exp with these?
can anyone help?
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.
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.
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.
so the population has gotten a little bigger has spred to the glass thoes little bastards are tough. went over it with my alge maganet several times and the are still there, i think that i will try a snail or two mabey that would help i think they have killed a few of my white clouds, and i believe that may be that reasoning behind my betta dying that anubus plant was his favorite place to hang out, if all else fails i guess i will just scrape them off the glass and get rid of the anubus, but i wanted to avoid that if i could.
I read that brine shrimp are a favorite food of hydras and you can starve them out by feeding your fish flake food. It's just what I read, and yes, they are really only harmful to fish smaller than 15 mm. If I hear of a good way to get rid of em besides chemicals I'll post it. I always thought they were cool to have but I guess it depends on the fish you have.
