Someone remind me as a general rule what is the load limit for slatwater fish/gallon? I currently have 4 fish (secretive wrasse, fairy wrasse, Yellow Coris Wrasse, and clown fish) I want to add another fish, but am concerned that it will be too much. Also if Brian or Christina happen to be reading I would like to get a Christmas or Leopard wrasse will the wrasses tolerate each other? So far I have had no problems with the other 3 being in the same tank.
