I bought a rock with some orange zoas on it and when I put it in my tank I saw some type of anemone. I think it's either a tiny rock flower or an even smaller rbta. The tank it came from had a rainbow bta in it so if yall think that's what it is then I consider myself in luck. How long do you think it will take it to get up to size? Rn it's about the size of a penny.
