I was at a store today who had a 6 inch by 4 inch rock of acans. Probably about 100 polyps. It was pretty drab brown and green. BUT, inside 3 of the heads there were pencil eraser sized blotches of bright orange and dark blue. Does this mean at one time these acans may have been colorful? I know absolutely nothing about acans. They dont want much for the rock, under 50 bucks. Is it worth getting them to put under t5 to see what happens?
