Is my betta's gold face normal? Does it need a heater in warm Texas?

Bettas are tropical fish and do best in water between 78 F and 80 F. A heater is typically required to maintain stable temperature. Rapid fluctuations in temp can be stressful. You should also check the water quality and chemistry. Poor water quality can cause the symptoms described. Filtration and regular partial water changes are necessary to keep a tank clean.

Cold water can affect activity in fish. Bettas are tropical fish and do best between 78 F and 80 F. Check the water chemistry also. You can use a home test kit, such as the API Master Kit, or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform a partial water change if necessary to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Diet can influence color, so it is possible this is partly to blame for the color change. There are diets that can be fed to enhance colors.

Check the water temperature. Bettas are tropical fish and do best between 78F and 80F. Low temps can affect activity in fish. If temperature is normal, check the water chemistry and perform a water change if necessary. Use only aged or conditioned water that is temperature matched to prevent stress or shock.

The water temperature should range between 78F and 80F. You can use a submersible heater. Make sure it has an adjustable thermostat to control temperature. You should also have a thermometer in the tank to monitor water temp.

The ideal water temperature for bettas is between 78 F and 80 F. Check water quality and perform a partial water change if necessary. Used aged or conditioned water that is temperature matched to prevent shock or stress. If he won't eat pellets, try soaking them in a bit of garlic juice. This can serve as an appetite stimulant as well as an immune system booster. You can also offer freeze dried (or live) bloodworms, brine shrimp or tubifex worms. The "wiggling" when he swims may be normal for him but check his fins for signs of fin rot which can make swimming more difficult.

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.

Maintain pristine water quality via filtration and regular partial water changes. Use only conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78 F and 80 F. You can try an "all in one" product, such as Lifeguard by Tetra, to treat the condition. Find it in the local Petco or online. Follow label directions carefully and remove the carbon filter insert if indicated. https://www.petco.com/shop/en/petcostore/product/tetra-lifeguard-all-in-one-freshwater-aquarium-treatment
