Alright so I set up my sorority night before last... it's 5 girls in a 10 gallon. You can see photos in my album or in my picture thread. The nipping/biting seems to have tapered off, but the runt of the bunch (and also one of the most defensive/aggressive) still isn't eating. She was in rough shape when we got her. She has tried a couple times to nibble, but the pellet just pops out and eventually she swims away (she's a loner and hates being by the other girls, even to eat). I tried feeding her in her little hiding spot, but same deal. I'm worried since she was the one in the ickiest water and who wouldn't eat the night I acclimated them to the tank. I know stress about a new environment can cause this, but when do you start worrying? I have a few piggies in the tank!
:) I appreciate the advice. I've only had single boys before.
