I have a 30gal. reef tank which contains a blue damsele, 6-line wrasse, and a clownfish. Could I add another fish? I'm thinking about one of the dwarf angels. Should I just move the damsele to another tank and then add the angele?

You should have no more then about one inch of fish per 5 gallons of water of one inch of invert per 6 gallons of water. So, you got 6 inches of fish available for your 30 gallon tank.

Does that go for reef tanks or just marine tanks?
