heat or not

never would of though that would be to much for that tank still seems to be plenty of room. How many gallon would i need, or how many should i have in there?

with your current stock, I think you'd be fine with the 100 gallon you want to upgrade to. I would personally jump up just a little more and get a 125. A standard 125 is a bit wider than a 100 and just looks a lot classier for two oscars.

You do need a bigger tank with that stock list. I'd look for a 125. I don't run heaters on any of my tanks. As long as your house in in the 70's you'll be fine.
