Hey Im setting up my tank for a bimac, but I have a temperature question. I know that bimacs like a temp around 66-72, but I have read that people keep them in water a bit warmer than that. I know that the colder the temp, the longer they live and the less active they are. However I don't wanna buy a chiller if I dont have to. So how high can the temp be for the bimac to live comfortably? What is the temp of your tanks?
