Room temps will do fine as long as it doesnt get too hot.
Feeding depends on the size of a fish. When they are small I would feed everyday. As you approach the size that you "want" start feeding every other day. Eventually a full grown probably only needs to eat three times a week to be content, but should be fed good portions.
These fish do get big, but they are nocturnal for the most part, and spend pretty much all day sitting on the bottom. Not necessarily something I would want, but go for it if you can provide the space.
