Re: [GSAS-Member] Hydra in Daphnia culture

[haika@drizzle.com]

But does it also kill the daphnia? I've had sporadic outbreaks of hydra in
my daphnia containers, but usually it's just an isolated container and
it's usually an inside one....not in ALL my daphnia culture containers.
Maybe that's why we've got 10 culture containers at work, and I've got 10
more at home (with 2 inside containers/rest are outside) + 2 pools that
also have daphnia that bloom occasionally. Between all those containers, I
usually have some clean ones to repopulate an infested one after cleaning
it out. I've also got a few hydra right now in my red-arc
pencilfish/sparkling gourami/thread-fin rainbow tank. I was curious
whether the little gouramis might take hydra, but I think that may be a
characteristic of the Trichogasters....my little guys left the hydra alone
(grump).
