I have 4 red eye's.
1 was the last of 3 from about 9 months ago when I started back in the hobby.
I got 3 more about 3 months ago to get him out of his corner.
It seemed to have worked but today I noticed 3 of the 4 have .. basically a swollen lip.
Can't tell which is which anymore but the one that is fine is smaller and shows less posturing then the others.
Both lips are swollen but the bottom is protruding and red below it.
They are not schooling and when they are close they nip at each others sides.
They don't seem to have any problem with the rest of the fish.
I'm just worried it's not just behavioural and could be an illness, disease or parasite.
They are all eating well and acting as usual, so I don't know..
Suggestions welcome
