Tank size?

[fishoholic]

We have TWO tanks set up right now and we are thinking of putting all our fish into one fairly large tank. I'm thinking we'll need a 250-300g minimum. These are all the fish we have: large Salfin tang, large regal tang, yellow tang, small lavender tang, large foxface, sadleback clown, scooter blenny, yellow head sleeper goby, 2 prec.'s, green clown goby, mandarin goby, small CBB, and coral beauty.

Yes I know it's a lot of fish but right now they are in two different tanks. The plan is to get the new tank up and running and then add all the fish at once, so there will hopefully be no fighting. I realize it's a lot of fish to add at the same time but I really think it's the only way to prevent a lot of possible fights.

What size tank do you think we'll need?
