If you're a bird, I'm a bird
My 150 has two firemouths, two texas, a salvini, and a green terror. The tank had two heaters and was kept about 76-78 degrees. Anyway, one of the heaters brought yesterday, and now the left side of the tank is at 78 and the right side is at 72. ALL the fish are staying on the cold side ALL the time. Should I leave it like this, or are they just being weird? Nothing else in the tank has changed, so I know they are not scared of a new rock or something, maybe I watch my fish too much...
