Hi I have a divided betta tank, it is a 5 gallon with two adult male bettas. I just happened to notice that the one the left side is a bit lazy :/ He seems comfy but he always stays by the divider and by the heater(the heater is on his side of the tank). I was wondering if this may be a sign of an illness?
