Hey! I have a medium planted 25 gallon tank with one and six rasbora: 5 Harleyquinn and 1 pork-chop. Two of my hqs are white and kinda lethargic. They look like they are peeling. One has a bitten tail. I have seen the pork chop bullying at one of them. WHAT IS WRONG WITH THEM and WHAT SHOULD I DO? Should I separate? I have a breeding box that I could put them in. Also, I am going to add another 3 of them. Should I qt the 3 all alone?
