I have a school of ornate tetras there's one male that is aggressive towards other males while he's hanging out next to a female, he also loses his coloring one day but it's back the next, I see no eggs or anything for him to be acting this way but him losing his color (almost white with no red) has me wondering if he could be ill, I will try to get a pic but him and the female are hunkered down in a thick part of the plants
