I have a mini bow tank that had goldfish in it about three weeks ago when they ended up dying (long story) so the tank (water) was cleaned out and water tested is perfect as of last night. It has been running ever since. My question is this. Can I just put a Betta in it? The tank is cycled from the gold fish, gravel and filter have not been cleaned or changed. Is it safe to use? There is no heater in it as well.
