I set up a tank using established rive rock a local dealer in Boerne had in his tank for almost a year. It had a healthy growth of Caulerpa and the tiny sprigs on the rock have grown well for me. They were infested with Aptasia which were easily removed when I set up the tank and have not come back.
There was one red anemone on the rock and he is doing great, eats 1/2 a silverside each week and is about 1.5 inches in size. Can anyone ID him>
