Re: Hydra


Hi,
I tried paradise gourami (it is not exactly gourami, but still labirinth 
fish!) to eradicate hydra, and they DID NOT work. All they did was 
spawning. I remove all fish and did copper treatment for a week 
(coppersafe medication). I treated for several more days after I did not 
see hydra, and a week ago put fish back in the tank. Today I saw hydra 
again! I will try to heat the tank soon.
I heard pearl and giant gourami will also eat hydra, but did not try by 
myself.

Cheers,

Lilia
