Help. Have green hydra... what do I do?
I’ve had my tank going for 2 months now (250 l planted, fluval stratum) Lots of baby shrimp now and snails (bladder and Malaysian trumpet) .. I just noticed green hydra all over the glass. I wiped some off yesterday, but I’ve spotted more on the plants. Think I’ve got a significant outbreak. They’re tiny, about 2-4 mm long. I also spot treated with a small amount of excel which killed a few. But there are to many.
I have been feeding baby shrimp food twice a day... so may be over feeding the tank...... I’m assuming that’s what’s started them off.
How dangerous are hydra to my shrimplets?
I’ve read that hydrogen peroxide tank treatment (1.5mls per 4.5litres of 3% H2O2) will kill the hydra but is safe for my snails and shrimp. But I’m worried that it will kill off my biofilm. I didn’t want to use anything that would affect my snails...
Any advice would be much appreciated!!!!
