Can someone help me out? I am confused as to what the ideal temperature is for Black Moors. I have been told by Walmart, PetSmart, and some other sites that it is 68F-72F. I have also been told by Petco, Tetra, and some other sites that it is 75F-81F. I truly do not trust Walmart or PetSmart because of some issues that arose right after purchase of these little guys and their former tank mate as well as some bad advice given to me regarding these fish. Can someone please help me out here. They seem to thrive better in the warm rather than the cold. Please keep in mind these fish have been sick recently and are in the process of recovering. Any advise is much appreciated!
