my first batch of coral. think the name of coral is leather. The second day in my tank had opened very nice. however on the third day it jus closed til now. the surface like a layer of wax. dun know it is dying or not.
How is it harmful? It looks fine to me. I got two of it. One about 50 cents coin size the other is smaller than a 5 cents.
Kurt Cobain, yup got it from WAKAI.
