My tank has been up for almost 10 months. Right now I have coral beauty, maroon clown(not aggressive.Been in my tank for 6 months), pink spotted goby, yellow tail damsel, coral banded shrimp and a mexican turbo snail. I have a 105 pounds of live rock in my 75 gallon tank. I was wondering if I would be ok to add a mandarin fish to my aquarium. thank you
