29/30 Gallon Tank -- Temp. Issues? Tropical or Gold Fish?
My girlfriend and I are setting up her first aquarium. It is a 29/30 gallon tank, we filled it up with water, purchased a new filter, got some living plants, can't remember the name, but the ones that gold fish like. However we have an issue, our tank seems to be running hot. We originally used a heater, after filling up the tank with cold water, to attempt to get up around 74-75, for what we hoped to be gold fish, and a pleco. However even with the heater off the temperature has been upwards of 80 degrees, which we are aware is way too hot to put gold fish in. We're not sure what is causing this temperature fluctuation, if it is the overhead light, ambient heat in the room, or maybe even a broken heater.
We were curious of a few things, 1) I've had a pleco living with gold fish, at room temp. very happily for many years. What is the ideal temp. and or a happy range for those type of fish. 2) Should we shift our focus to tropical fish, if our tank can't stay cool? 3) Any ways to figure out exactly what is causing this, and a reliable way to keep the temperature stable. 4) Suggested fish, if we have to make a 180 and go for tropical fish.
Thanks a lot.
