1.5" x 1" WYSIWYG and fully aquacultured by WWC! The WWC Super Red Polyp Clathrata can be considered one of our Legacy Corals! We've growing this beauty our for more than 10 years now and it is always a crowd pleaser! The insane canary yellow tipped corallites and always red polyps, plus a relatively slow grower make for an Acropora that never seems to lose it's value as it always sells and fast too! Place this Acro about pretty high or about 350 par for best growth and coloration. To really speed up the growth rate of Acropora, target feed them by squirting a small amount of excellent quality SPS frozen food once or twice per week via a large syringe. Best results will be found when you place your recirculation pumps on feeding mode so that the polyps can "catch" the small particles of food floating by. If you don't have a feeding mode, set a timer as you do not want to forget to turn your pumps back on as that would be really, really bad.
