I have a 12 gallon eclipse, and 1 yellowtail damsel and 1 coral banded shrimp. I really want to get another fish (particularly a Royal Gramma). I posted a question a few months ago, but my LFS
has told me that he has personally put the two fish together in such a small tank. He told me to just make sure the Royal Gramma has been at the LFS
for a couple weeks and I should be fine. Please help me, even though it is a damsel currently in my tank, I have taken a liking to him and do not want to trade him out or put him in a dire situation. Thanks for your help!
