Just wondering what the deal is with angelfish and red gills....we have quite a few at work that look normal, and quite a few that have bright red coloration on the gills. I was reminded of it looking at PopPop's thread here (http://www.aquariacentral.com/forums/showthread.php?t=180526) because some of his angel's show the same redness. Is it a color morph or a water quality issue? If it's the water, why does is only affect some consistently and never the others? Thanks!
