My 6" Caribbean spiny lobster has killed 3 fish. A naso tang, California stingray, and cleaner wrasse. He's in a 150g tank. I would like to add more fish, and I have a 20 gallon tank with 3 clowns and a damsel (I rescued two of the clowns). Could I move the clowns into my 18"x12" refugium and put the lobster into the 20 and get more fish???? I don't want to give him away but want more livestock. Please please please help!!!
