I, who have trouble in other departments when it comes to the our reef tank,, have had very good luck with Clarkii. They are about 5-6 years old and recently spawned hundreds of fry. They are a hardier than other clowns, at least mine have proven what I have read about them, to be true. They are the least aggressive of many of the Clowns, but upon preparing for the ritual of egg laying, had a very difficult time keeping rocks and corals in place. I mean large rocks. They did get very protective of theor space.
The male who has never shown any aggression before, is now much more demonstrative than the female who has always been very protective of their massive "colt like coral". Have never been able to identify exactly this particular coral. . But, you might try a Clarkii or two, unless you would prefer other colors. These are Blackfoot Clarkii. The male changed over time to a yellow foot, and kind of darkens up now and then. They were wild caught, which now when choosing fish I would never purchase wild caught in that the methids for catching are often deliterious to the reef and fish.
Their relationship to their chosen coral is endearing and entertaining. It took them at least two years to settle on a leather. :happyfish
