kribsincrib-- well, I've had the oto for . . . 5 days now. The tank he was taken from was very clean, and the fish looked well, but I'm not sure how well fed he might have been with tons of other otos and no signs of algae around. Well, I'm trying to fatten him up right now . . . there's the cucumberas proof, and I think I'll try growing some algae separate from the tank for him too.
