Bold move Adrian, sps corals are not the easiest carals to keep but i guess you have to start somewhere if that's your cup of tea. One sps coral that stand out more than any other IMO on the easy scale is the Orange Montipora Capricornis. The problem with the ones mentioned above and even other Monticaps is that if water condition is poor, high po4, high nitrates and such they turn brown. What i find extraordinary is the Orange Montipora Capricornis doesn't. This is the only sps in my tank...
I got this piece three years ago, survived all kinds of mishaps. Grew to the size of a dinner plate twice with pc bulbs. Sold them and still have more to come...
