Hi Since (over)dosing Flourish Excel to get rid of BBA I have lost two of my four blue rams. A third is now also looking quite ill. The symtoms are bulging eyes, darkening colour and general lethargy before expiring. Has anyone experienced Excel causing such problems or is this just coincidence and the fish have some disease. None of the other fish seem to be affected but I'm a bit concerned as my daughter bought me a pair of Apistogramma agassizi for Christmas and would hate to 'murder' them at this festive time.
