Jason, The only fish I know that eat hydra are the different color forms of the Three-spot Gourami (Trichogaster trichopterus) and they only eat them as a last resort. You would have to starve them before they would eat them. Your best bet would be to remove all the fish and treat with a copper medication. Not a nice thought is it? Hopefully someone else will have a better suggestion. Mike Wise ruddigar@home.com wrote: > Is there anything I can put in my heavily planted 5gal breeding tank > that will eat hydra.
