The tank has been set up for 5 months now. Rock and sand pulled from my three y/I set up. Acans seem to really like this tank. I have some christmas favia, war coral, chalice, leptastrea and acan enchinata. But I plan on adding acans only as my new additions. I think I have 9 mini colonies. I also have two derasa clams and a squamosa. Here's some preview pics with actinics.
