The carpet that is in Abran's tank, the one with the saddleback, used to be mine. It is a Haddon's anemone. I had my carpet for almost two years after rescuing from an uneducated reefer. The carpet had widdled down to something smaller than 5 inches in diameter due to the lack of feeding techniques and improper lighting (he was in a 29 TALL with one dinky flouresant bulb!!). So I took him hoome to my tank that had "better" lighting (3 flouresant bulbs) in a 30 gallon. I fed him frequently and began to notice a change in size almost immediately. A few months later I moved to Houston where I upgraded my tank to a 72 gallon with PC lighting. As soon as he was introduced to the PC lighting he almost tripled in size. He was the center piece of my tank and pretty much ruled it with few problems, well except for the incident with the pump. When I had to tear down my tank, he had grown to something around 12 inches or so. Now he resides happily in Abran's tank where he seems to have stayed the same size and color. The only difference I noticed from PC lighting and Abran's lighting (which I have no clue what it is) is that you can see the stripes better. PC lighting will work for anemones, but it is all dependant on depth of the tank. Ideally, MH and VHO whould be recommended, but carpet's are not entirely photosynthetic either, they rely on the meaty foods they capture to get a lot of nutrition and growth. Mine did very well under the PCs, but I also fed it regularily (like every other day or so, let alone the few fish it managed to make a meal of).
These type of anemones have poor survival rates do to improper collection, so the damage done can be fatal if the collector doesn't carefully remove them from the rocks. Remember, never get an anemone to make your clown "happy", get one only if you can properly care for it.
