I got a blasto frag last year and its now up to 4 polyps, it's green in the middle with a red ring around the polyp. I went to feed them when i realised a new polyp had started to grow and it is all green with a bluish middle! I thought maybe a ricordea had self propagated but then realised i had moved my ricordeas a long time ago. But it was definitely a blasto. maybe it just looks like that because it's new? i cant get a pic of it because its too dark where the polyp is i could try a flashlight.
