I know nothing about bettas. I bought one today and just hoping he lives through the night. He is not very active and swims around the top of the tank a lot. What does that mean? I have him in 2.5 gallon tank with plants and castle and rocks. I have not got a heater yet but plan too soon when i can. Will my fish still be fine without a heater. I don't know the temp of my water, will this cause a problem?. I had goldfish in the same tank yesterday and they were dead the next morning. So I am kinda worried here that i am doing something wrong.
