My boy Joey is in the picture. He is a multi-color CrownTail. It's been 10 days since I brought him home. He had red color under his gills then. Even now his gills seem to be in the same condition. I was reading about Betta disease and I came across something called gill inflammation. I am not sure if he is suffering from this disorder. Also his head was not too grey when I got him. Now his head is getting darker and darker (brownish-black). Is it some kind of infection or is it a part of his growth process? He is smaller than most of the bettas I saw at the store. I am not sure how old he is.
He used to eat protein pellets during the first week (he always ate very less, like 2 pellets if I put 5) after which I fed him some freeze-dried bloodworms once. Since then he is eating only those bloodworms. He no longer eats the pellets I usually feed him. Instead he takes one in and then spits it out.
I really not sure if something is wrong with him. Please help me.
