Just got a tomato clown from LFS. It looked great in the tank and the owner said it had been in that tank for a month with no problems. So i decided to quarantine a fish for the first time in my life. I learned the hard way, but its day 2 in my quarantine tank and he's always either in between the powerhead and the side or wedged under the heater. Is this bad?? I have a small heater, a 20 aquaclear hob filter and a small maxijet with a koralia water deflector on it. I tried feeding him rods with selcon and vitachem, but i didn't see him eat much. he would keep eating the same piece and spitting it back out... please help thanks
