I just got my Orange sale back puffer about a week ago. Recently I have found out that his color has cracked on his back, the crack is white when his back should be green with and orange saddle. My ph is 7.6 my ammonia is zero, my nitrite and nitrate is zero and my water temperature is 75º. In my tank I have two arcane cichlids and a blue yabby. I don't know what is going on because this is the first time I have had this type of freshwater puffer in over ten year.
