hydra

I found these turbine shape micro-organisms in my tank. They seems like hydra where they have a stem and branches, but hydra branches are thin but mine is big.

Hello, I want start a new project. I would like use a filter Hydra without sump. What do you think? it's enough? maybe is better ad an other filter?

Does anybody know how to get rid of hydra WITHOUT killing my shrimp? I dont like having all the green things hanging off everything

Ok I made a post a while back about my betta fish Falkor and him losing parts of his fins, after a while ive pretty much ruled out everything but him being a biter so I just left it and he was fine. Ever since then, everything started to go downhill. I've had three shrimp across like 5 months...
