Cheers, I would also say it's not an illness as none of my other fish have it but it's just a bit odd that both eyes are inflamed, I don't think his vision is that good either, he does seem to be bumping into things a bit. I was wondering if it was another fish, I have an australian blue lobster in there but he's very docile, I know what people say, but this one lives happily with my fish, I have clown loaches and pictus catfish that actually sleep along side or underneath him and at times they go around cleaning him, he does get a bit grumpy if they try to nick his food, it's as if they have an understanding but if anymore fish are added to the tank, he'll go for them, odd.
