So I goy my regal this past Saturday, haven't been able to get him to eat. He's pertyy eactive now m seems comfy around all his other tank mates, constantly swimming thru the rock work. Diff types of frozen, flake, pellets & even veggies n nothing. He picks my rock all day, I'm sure that's not anywhere enough to keep em full thru out the day. I noticed a tiny bit of fin rot on it's tail today so I'm a bit worried now!! Any suggestions to help get him to eat??
