My betta fish's color changed. Is this a good sign for his health?

Hi, my name is Emma and I have a male half moon betta fish named pucker. I’ve had him for about three weeks now and just bought him a tank about a week ago. When I bought him from petsmart they ran out of betta food so they gave me this bug bites tropical fish and he ate it but didn’t like it. But I went back and bought him his food, which colour enhances. Today I went to go feed him and noticed his colour has changed, did it change in a good way? Also does he look healthy to you?

Hi Emma. Pucker looks fine. There is a little difference in the before and after images. This could be due to diet or water quality/chemistry. Continue to monitor him and feed the color enhancing pellets. Maintain pristine water quality via filtration and regular partial water changes. Symptoms that may indicate a problem include lethargy, loss of appetite, clamped fins or difficulty swimming.
