I have a 125 gallon reef tank and a 90 gallon 1/2 reef tank.
125 gallon has red lipped blenny,yellow tang,purple tang,royal gramma,shunk clown,percula clown, and coral beauty angel.
They all live in harmony with a 150 lbs of live rock.
My 90 gallon had 40 lbs of dead rock that we put 8 lbs of live rock in with and 20 lbs of live sand. We let this run for 7-8 months without anything in it. We would take pictures of fish from my other tank and tape them to the outside as a joke. We added a fox face,yellow tang, regal hippo tang,royal gramma, and a large maroon clown. Boy great move by our part. We have not lost anything but snails. They all live in harmony.
