Thank has been set up since march. There are 5 green chromis, 1 six line, two true percolas, 1 sand sifting goby, 1 hi fin goby. Have various leathers, Lps and Zoas. Have about 40 blue leg hermits, and 1 turbo snail and a couple of nerite snails. Tank is a 75 gallon and has a 40 gallon sump. Water perameters are in check. Doesn't appear to have a any saw dust like shavings around it. Also looking today the stalk seems to have a slight greenish tint to it. Thanks for any help.
