My new 5 gal tank is almost done cycling according to my results. I've had it for three and a half weeks. I've kept two Guppies in there ever since I got the tank, and three days ago put a Platy in there with them. The tank didn't come with a heater, so I haven't been using one. But it did come with a filter and a light. I have gravel, and a plant in there along with the fish. I was going to buy a heater this week for the tank, but I was wondering if the sudden heated water would stun the fish? I'm not sure if they're used to the water just being the way it is because all three of them are acting normal. Also, I found a rock outside I would like to put in the tank. I washed it off, and scrubbed the dirt off with a toothbrush. Would it be okay for me to put that in there or should only gravel be in the tank?
Can I still put a heater in my fish tank?
