So I wanted to surprise my dad with a fish tank that is all set up. He has gone to Hawaii on his honeymoon and so I wanted to make an Hawaiian fish tank. It is about 200 gallons and has a large rock protruding 40cm out of the tank which is full of water. Now I'm thinking what fish could I put in there? I want fish he would've seen because he is going scuba diving a few times. I've heard there are triggerfish but they aren't reef safe I don't think. I've heard that tangs live there and Zebra Eels are reef safe aren't they? I've heard they are Hawaiian. Sorry for dragging this on but thanks x
