One of my clown fish started swimming very funny this week, upside down etc. I've been keeping an eye on it and yesterday noticed a lump on the clowns side. Almost like an air bubble in it belly. I moved it to my qt Tank cause now it started laying on the bottom and other fish were nipping at it. Do you think this is SBD? If so any ideas how to cure this? I've read about feeding them peas??? and not feeding them for a few days to see if that helps????
