I'm going to hopefully be getting a betta for my room tomorrow, and I've got everything set up: 2.5 gallon tank, 1/4 inch layer of gravel, de-chlorinated water, a heater, and a safe place to put him that's away from direct sunlight and vents. I even got my fish picked out- he's a real pretty white spade tail (I think) with a blue/violet incandescent sheen and tiny royal blue spot on the tip of his dorsal fin. (I'm going to name him Shiro!) Now, the only problem is, my room tends to get very hot, very often- Even in winter I'll sometimes sweat, be it day or night.. And I live in Minnesota!
My dad says I can't keep Shiro downstairs because he's afraid "He'll stink up the house!" and I'm worried that adding a heater to my already hot room will result in boiled fish. I already keep the blinds down because my computer is in my room as well (which probably contributes to the heat) and turning the A/C up won't help me in a few months when we get snow.
Do I really need the heater?
