I have had my tank up and running for a week. I noticed this afternoon when feeding that my spotted raphael catfish looks bloated. I dont normally see him once I get home from work and turn the light on so trying to get a picture now isnt happening. He came out to eat and then he hid, as he has since I got him. He is still eating, Im not sure if thats good or not? Do I wait this out or act now and what should I do? Although Im not sure if it matters but all fish in the tank are juvies.
