when i got home my limas fins were all torn or missing, was missing a barbel and he had a big gash above his left eye. What should i do to treat him? i just put him in my 100g today and he was only in there for about an hour. he still swims alright and is currently in my empty 10g. hes about 5 inches, also who do you think hurt him? his tankmates are in my sig and the lights were on so as far as i know the catfish were all hiding.
