Hello everyone i'm new to the forums, and have just recently purchased a 70 gallon tank and have a few questions. I've done some research on each of these fish, but I was told to come here if I had any more questions about the fish. The first fish id like to get some questions answered about is a Red Tailed cat. I found a local pet shop that sells 2" Red Tailed cats, could anyone give me some info on what they eat and how often to feed them? Also how fast would they outgrow a 70 gallon tank? The second fish is a Peacock Bass. Ive done some research, but am not sure how fast they would outgrow a 70 gallon, also can it be kept with the Red tail? Theyre 3" atm, 1" bigger than the Red Tail. The 3rd is a Silver Arowana. He is currently 3" long and in the tank by himself. Would these 3 fish be able to live in the same tank together? I live in NY and it gets pretty cold during the winter, would I need a heat source to keep the tank warm? Any info would be greatly appreciated, thanks!
