Every once and a while I'll see my fish just rest right up against the heater or just next to it and they'll like crowd around it like it's a campfire... does anyone know of a specific reason for this? My tank is 80F so I doubt they're cold but I could be wrong. They only hang around it for a few minutes then go back to whatever they're doing and then go back later.
