Pay attention to there color, how open the heads or polyps are. Lighting is not the only concern here. Flow plays a very important role as well. Look each of these corals us online and see what they look like, read more into there requirements. Just type the coral name into your search engine.I have asked some people already but I recently got a neon green trumpet head, a green singulara some waving Xenia, a orange cap Monti and a leather coral where should I put these in my tank? In high or low flow?and high or low in the tank for lighting?
