thanks for all the kind comments
blueheaven, all clams are from irwana recent shipment, has quite alot of pieces when i was ther.
as ur can see that my sps was quite brown, actually i started as a lps tank and decided to try sps six months ago. mosts of my sps was bought cheap and brown, so as not try those nice and expensive sps in my tank and get stn or rtn.
i was glad that all sps show healthy polyps extension and growth. some of my brown sps has colour up very slowly. as currently using 2x150 watts so all sps was place high near the surface.
kindly hope that all sps experts can give some valuable comments and feedback
will update more pics when i go get myself a digi cam, currrently borrowed the cam from friend la.
