ive had this plate coral for 2months now . all going well but started to notice dark like patch forming on the tissue at the base . Its quite noticeable as the rest is pink?? What would make this happen ??

cheers

It maybe black band disease Matt! How is the water flow to your stony? It could also be an encrusting sponge(porifera) growing there as many sponges enjoy subdued light and dissolved organics, high nutrients due to being excellent filter feeders!

cheers mate!!
