That coral that looks like a nem is a torch coral. Its needs medium light and medium flow. Not sure how it would under two bulbs though. Its ana wesome coral too, make sure you look into them when you gt more lighting. Its always waving in the flow...lol
I also almost bought a RBTA today but my common sense kicked in and I didnt. I think if i'm gonna go nem it's gonna be a mini maxi for the 20g. They dont get to more than 6 inches and are very colorful adn they arent know to have clowns host it and it doesnt eat fish. lol

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
