Totally unnecessary. Water temps vary a lot in the wild during seasonal changes. Chances are the temp will only drop 10 degrees or so to be at room temp. Not a big temperature swing for a WC native fish.~ocean;3579932; said:alright forget the heater... lower the temp by 1 degree every day, then get rid of it...
As far as tankmates go, not much will work. They either beat up or eat other fish or get beat up themselves. I've had success keeping multiple bullheads together though.
