My male DT betta used to be mostly grey with a little bit of red in him. now he is predominantly red with a little bit of grey.
I noticed the change starting after he had a round of tailbiting. To help him recover I started doing daily water changes and changed his food to Omega One Betta Buffet pellets from the Hikori pellets. Since I was doing so many water changes I started using tap water versus poland spring so the PH is also higher.
He is acting normal, eats like its his last meal, and is extremely active. He lives in a heated 5 gallon tank, no filter. My water change regiment is 1 50% WC and 1 100% with housekeeping service
Given my WC routine, the ammonia is his tank never gets past .25ppm. I feed him once a day 4-5 pellets. Sometimes I do 3 pellets and freeze dried bloodworms to vary his diet.
Is his color change normal? Should I be on the lookout for anything?
