Today, I got a Vieja Argentea cichlid and my flowerhorn cichlid beat the living **** out of him so I put the Vieja with my 4 inch dempsey, the dempsey was beating him to so I tried to catch the Vieja on accident one of the big heavy rocks tipped over and slammed onto my dempsey and broke the divider so I got the vieja and returned him, to get a new divider...When I came back my dempsey's lip was torn open and had alot of skin hanging off of it. What can I do? what medicine should I get to help it heal? The flowerhorn was picking on him like crazy, thank god I had the divider... please comment the employee's at petsmart had nothing there?
