So I have this cap. It was an orange cap with orange polyps and was living happily in our 12g until one day some other coral (don't remember if it was our frogspawn or birds nest growing onto the base) stung the crap out of it killing about 99% of it off. There were 5 lonely little polyps left on a skeleton about 1"x 1" so we figured we would keep it and see what happens. Since then we have upgraded into a 29 cube and the little sucker took off like no other. It has almost fully grown over the skeleton....but....it is now an orange cap with green polyps. Definitely NOT the orange ones it started with. Has anyone had any similar experiences or have a reason as to why the polyps would change color? I do not currently have a pic because I suck at photography but I will try to get one tomorrow.
