They may be 2 males.. which could explain the issue.. or the size difference. I can't predict for you if it'll work out but I can say the stressed one will benefit from plenty of plants to hide in.
How long have you had them?
The 2 I have do "bicker" on occasion and certainly follow each other around but they've found peace.. after I returned the 3rd one. I have a male and female so that helps.. and they are the same size.. It is up to you if you want to wait out the size difference and see if that helps.
Have you tried to sex them yet?
