Need help controlling water temp so I can add fish
My 20g aquarium is in a room that's not air conditioned, and the water temps are swinging from 78° in the mornings to 84° in the afternoons. Unfortunately, I don't have an easy way to cool the room other than a fan in the window at night. This is an old house and it's not wired for a window AC unit, so that's out of the question. I'm hoping you guys may have a recommendation that won't break the bank.
I haven't put any fish in the aquarium yet, but I'd like to find something to control the algae that's starting to grow, and something that'll liven up the aquarium. It's fully cycled and has been planted for about six weeks. Everything other than the temps are looking good.
Are there any fish that can handle temp changes like this?
