Guppy Fry Tank - Hydra

[Damo.Lo]

Hey All

I Have a 5G Guppy Fry tank that I have been feeding Live Baby Brine and Hikari Micro Pellets, The Fry are 3 weeks old. I've noticed on the sponge Filter that has hair algae on it and the glass that I have a new tenant.. Hydra, I'm not sure whether they are white or green but are only about 4-5mm long. I would like to know should I let nature take its course and wait for the fry to be large enough to eat them? ( do they eat them?) or must I remove the fry and starve the hydra?

Thank you in advance

Thats up to you my friend. Hydra aren't generally harmful and shouldn't be a problem for your fry. They will make short work of them when they get bigger. I think they're kind of cool personally but I did have to sick some guppies on mine because I had a glass skater (Hillstream) that didn't like roving over them. However, this is just a guppy tank, I say keep the free food, that's my vote.

@xXInkedPhoenixX I was leaning towards let nature takes it course because they are fascinating to watch. just didn't want it to be something that can become un manageable 

thanks again

Yeah they could get out of control but you know how to do that. Feeding baby brine and fry foods definitely make them multiply but when guppies get big enough a couple days of fasting should make rather short work of a chunk of population.
