I just joined this site and I am hoping for a little help. I have a 180-gal tank that has been setup for about 2 1/2 years. The tank has been doing great and I have kept mainly live rock, sand, a large carpet anemone, a few soft corals and several fish. (I have a 1 yellow tang, 1 blue tang, 1 sailfin tang, 4 percula clowns, 1 pygmy angel, 2 scooter blenny, 1 damsel). I would like to add several corals and build this aquarium into a reef tank. I recently added some star polyps and another large anemone (purple long-tip) and after reading several blogs, I am concerned about having two anemones in the same tank. Is a 180-gal large enough for them to co-exist? I appreciate any help on the subject!
