just a quik question i have had my betta named blue for about a month now in a 1.5 gallon tank with 2 plants and a hammock leaf, water temp is 72degrees i feed in 1 or 2 times a day with tetrabetta pellets 3 or 4. I do a 40% water change every 3 0r 4 days after 2 partial changes i do a 95% water change. he is an active fish swims around quite a bit, he also comes and greets me everytime he sees me. i did a 95% water change yesterday and today i noticed he has a tiny (looks kind of like a gold flake) glittery or shinny spot on the end of his gill kind of by his lil finn. he eats and seems to be ok. all i want to know is that can his color of face change through out his growth or life? or could it be something else?
