Hiya, I have recently just bought a yepezi ray and it has never been mentioned to me to cover up my heaters and unfortunately my rays has managed to give herself a small burn and now it just looks like a little hicki (love bite) on the underneath or her disc and I was wondering if it will just heal on its own. Ive bought a new heater now with a guide and I do a 10 15% water change a day at the moment. One more question... is plecs and rays a no no?
