mate cosmetic surgery on fish is as wrong as color dyeing fish. at end of days its for your benifit more than the fish, ive had a rtg with de so bad his eye would role back, and that only just caused him mild annoyance at best... he was still 100% healthy and able to out compete over aros for food.... if you are thinking of operating because u brought a silver and dont like the de then u cleanly didn't do the research before u brought it... if it bugs u that much what u need to do is sell the aro with DE and buy a black!
