Wal-Mart has great deals on tanks but the hoods they come with are crap my 5 gal. I got from there that came with a hood and after about 2 months the hood died I tried changing the bulb in it and it still didn't work.I read the reviews and alot of people had the same problem.Your best bet is getting the 10 Gal. kit at petco it's a good deal and a nice tank.
I decided that Im going to make a custom tank :P With my dads help. Sheets of glass are WAY less expensive, so Ill be able to make a pretty big tank. Plus my dad has lots of experience in this department :P He used to be a fish hobbiest :D
