I have a newly set up 28gal jbj nano. With about 70lbs live rock and 3 corols. Button polyps, ducanops, and candy cane coral. Clowns have been in tank since the 24th of december. The black spots are on the orange sections of the fish not in any certain are just random spots every were. I would say 6 to 8 spots on each. They are currently pretty small but worried they may get bigger. I have noticed their color darkening which i know is common depending on what feed and the lighting. But dont know if this is disease or weir coloration changing and should i expect them to be getting darker. They are active fish with a very healthy appetite and besides a few gently shakes, they show no other aggression please help. Any ideas or thoughts would be helpful. Thanks:sad1:
