the wife and i was walking around petco last night looking at fish. and there was this African cichlid that somebody brought in i dont know if it got to big for there tank or what. but i have never seen one like it. it looks like a big convict but has the hanging fins like a angel fish. i got some pics of it with my phone but arent to good i will try and get some better ones with a actual camera. but my question is it looked fine in there tank but when i woke up this morning its losing scales. i have never had this problem. before i added the fish i did a 50% water change cleaned all the rocks and all of that. the tank is a 100 gallon i have a 9-10" oscar a 8-9" jd and this new fish. i bought some parasite medicine to put in there. to try that and hope it helps anyone have any idea why this is happening to this new fish?
