I'm not sure, but I think it's a green slimer.
Most
SPS like to be in the upper range depending on your lights. What I do for my SPS is I check
calcium, KH, and
magnesium levels weekly. SPS are mainly made out of calcium and KH so they're very important so most people when they have a mature SPS tank (fully SPS colonies) use calcium reactors. I'm getting one next summer probably
So what I do is:
-upper range is best, (you don't have to if you have strong lights)
-feed them refrigerated liquid formed oyster eggs once a week (or similar)
-water parameters are in tip top shape
-When you put them in your tank, if they're brown and every thing is good, move them to a different location. Leave them for about 3 or 4 days and if they're still brown, move them to another place
-good waterflow
so that's basically what you do to keep SPS growing

Once their big, they'll consume a lot of calcium.
