I just recieved a Lavender tang from a winning raffle at the SCMAS meeting. I dont know much about it but after acclimating it i introduced it at night with just my lunar LEDs and it did fine. My 3'' yellow tang was a bit of a bully and did not cause any real damage. Just a small nik on the lavenders face. the wouldn't stop chasing one another for a few hours. Than in the morning they were perfectly fine together. This is a beautiful fish and i am glad that they now get along. The yellow tang would of been the one to go if they didn't get along... Thanx Southern California Marine Aquarium Society.
