Hi,
i purchased 5 otto catfish on friday and they were in the quartine tank and this morning i found 3 dead. I put some discus waffers in there but i wonder if they went hungry???. Checked ammonia and that was fine so imm not sure whats happened. Im pretty pissed off as they were $8.95 each for about 3cm. Any help would be apprecieted

Cheers Axl
