Check the water chemistry/quality. This can be done using a test kit at home or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites. Elevated levels of either can be toxic to Opie. The nitrate level can be 40 ppm or less. Partial water changes can be done to stabilize chemistry and improve water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Bettas do best between 78F and 80F. Use a submersible heater if necessary. Diet can also affect coloring. Hikari and other makers offer pelleted diets that may enhance colors. Look him over for sins of illness (redness, sores, swelling, black spots, etc.) or injury such as frayed fins. A bit of plain aquarium salt (NOT table or Epsom salt) can be used as a general tonic to reduce stress, improve gill function, treat minor infection and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days then reassess the condition.
