A few months ago I bought a blast from a LPS. It was one of my first corals I purchases and I was super new to reefing. But I'm having doubts because of how small it is. The colony is only about an inch in diameter. It seem way too small to be a blasto. It hasn't grown at all but is puffy and eats when I feed. I just want to know if I was told correctly about what kind of coral it is.
