Do you really have 3 clowns, a hippo tang, a cleaner, and a condi in a 39 gallon? Tang Police?? I am suprised nobody has said anything about that yet? They are normally all over people for keeping a tang in anything less than a 150 LOL!!! Good luck, read, read, and read again so you dont kill everything in your tank because that is worse than just waiting the few weeks for your tank to cycle...
