Pico corals that stay small but look large

[thecouch]

I've seen a lot of small 1 to 3 gallon pico that look like regular size tanks until they put a can or there hand next to it. What's the secret to making rocks look like there in a large tank and what coral to stock. What corals will not over take or harm other coral in a small tank. What coral will stay small but look like popular large corals. Or any secret to maintaining coral to stay small

Button scolys, what are they?

I've seen an emergence of these little mini-scolys (button scoly) around, and I'm trying to get some more info on them, and what exactly they are. Thanks!
