I'm trying to give my tank a good natural look I already have some purple anemone and a xenia colony that doesn't seem to be doing too well... worried about that one too... any info or advice is highly appreciated... being a new hobby I would like to keep things alive for quite awhile... trying to find info on the net about some of these critters is quite difficult and there just isn't any books sold in this area that explain the care of them too well...
