Hey guys so ive had my blood parrot for about 3 months now and he is about 3 inches. He has had the black stuff come up on him a lot but i know how to treat him for that. My main concern is his gills. They are super puffed up and there is like a really thin whit layer at the end of the gills that just flap around. When he eats, whole food chunks just fall out and are left behind. He swims around normal and seems happy as ever. Is this normal or is there a problem? When first bought they were not like this. I will post a before and now pic. His tank mates include 2 small bichirs, a silver dollar and a pleco all in a 20 gallon (i know its small, its just temporary until i can move him to the large tank)
