I definalty have an acan now it is a 3 head acan. deep red circles with white and blue stripes. I put the frag high in my tank getting a decent amount of light. what do you guy or gals have to say about them. growth,lighting,flow?
Acans are as hardy as they come. If you want great growth and color ~ feed them. Mysis and cyclopes are good choices. The other thing to worry about is too much light washing out the colors. They are not a high light demanding coral.
