Who Gives A Fish Forums

Yep, canisters can be brutal. I switched to a sponge and never looked back. Also, try feeding 'em near the front for a few days. Might help teh fish associate you with food instead of hiding. Works like a charm for shy fish.

Hey, my discus did the same thing when I first got them. Turns out they just needed time to chill. How long you had yours? If it's recent, they might still be adjusting. Also, check if the filter flow's too strong. Mine hated the current at first.
