What size tank?
Well I plan on getting a large saltwater tank when I move into my house in a little less then a year and would like to do a tank with large fish like tangs, angels, butterfly's, and what not. I would love a 150 gallon cube but am unsure if this is enough swimming space for tangs. If not What size cube tank would work? Id like 150-200 gallons. I know a 200 gallon isn't a cube but I just want something that is really deep because I don't want to have like a 7 or 8 foot tank.
