I've had been taking them out of the tank to feed for about a week or two now. Today when I put one of the little guys in the feeding container, it kept trying to climb the walls as if it wants to get out. Not even food will calm it down; it just ignored it like it didn't see it. So I placed it back into the tank and tried to offer it food there, but he kept ducking and hiding as though he's scared. Have I overstressed it? I feed it twice a day (a daily meal split into two feeding times) and I do a partial water change once a week because I don't have a strong enough filter.
How long can it go without eating? It's about 1.5 inches long.
