Finally got rid of my 2 yellow "Acorpora Eating" gobies yesterday. Thanks Tigger for taking them off my hands.
My Acroporas are extending again after months of being closed.
Definitely not recommended for Acropora and SPS tanks. They don't need to be nesting to eat polyps. Mine had been eating my Acropora and Millepora. I believe both of mine were males. Too bad, they were cute little guys.
