Bettas, and fish in general, may lose color due to old age. At 2 years of age, your fish is getting old. Their lifespan is between 3-5 years, average is closer to 3 though. Maintain pristine water quality. Test the water chemistry to confirm an absence (0 ppm) of ammonia and nitrites. Nitrates should read 20 ppm or less. Partial water changes can be done to stabilize chemistry and maintain quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Bettas do best between 78 F and 80 F.
