So, my system has been stabile for sometime now which means it is time to shake things up.
I have always had a desire to add a small domino to my system as a final fish. LFS
has some small healthy looking ones in right now and I am thinking about putting one in QT this weekend. It would be about 1/2 size of anything else currently in the tank including my chromis. Yes, I know they can get big and mean as I had one a couple of years ago.
In general dominos are considered reef safe. It comes down to a territory issue which should not be an issue since it will be the last fish and everything else is already established. When I had one before it schooled with the 5 chromis I had at the time.
So, how many are keeping damsels in their established reefs?
