Have a staghorn greenish blue near the top of the water. It is under a 6 bulb t-5 Aquaticlife system. Was a small branch 6 months ago, now has like 30 branches. Grows incredible. Have done great with that, can anyone recommend another sps for me to try under that lighting. Have also had a clam in there for over a year, and it just keeps getting bigger and bigger. Thanks for your time.
