I rescently aquired a what I think is a 33 gallon hex type tank. I have a 10 gallon freshwater and I was wondering if the new one would be a good tank for a saltwater tank. I am wanting to just have fish and live rock in it. NO coral at this time because I am new to this so I want to be careful. I am new to this so all of the help I can get will help. Also what type of fish can I put into this tank. I like a lot of color. Thanks.
