Quite small in mine. Also seems to move around a lot. Seems like it might like very low light and be a very slow grower in my experience.Guys is this yuma big in your tanks? I got 2 small ones and a baby but they are really small, compare to other Yumas not sure why. A zoa polyp is bigger then it.
I see so is as big as a ricordia mushroom. I guess I have the midget version .They do fine in my tank. Need to let it get dirtier... View attachment 40561
