welcome to the sps game, thats why many well know and aqua cultured frags are worth every penny IE: red planet, cali tort, most birdsnests, and validas. on the same end lots of aussie mini colonies are very cheap, however are not that hardy. I have seen sps melt away for no apparent reason with steady parameters, temp and salinity ect. and thats part of why I like them(the challenge). IMO the most amazing tanks are sps dominated, however being able to keep and maintain them is incredible. I have had red bugs, monti eating nudis, stn and rtn and been completely destroyed. yet I haven't stopped. not my tank, but this is my inspiration.
