Pet's info: Fish | Unknown - Fish | Female | unspayed
Hello. I have a female Koi Betta fish named Coral. I estimate she is about 8-9 months old. So far she is doing very good but for the past few days her color has faded and she has been near the top of the water and she has not been eating. I am not sure what is wrong with her but do you guys have suggestions for extra vitamins or different food. Thank you so much !

Check the water chemistry. Elevated ammonia or nitrites can drive her towards the surface. Perform a partial water change daily to stabilize chemistry and maintain water quality if indicated. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78F and 80F. Plain aquarium salt (NOT table salt) can be used as a general tonic to reduce stress, improve gill function and aid in any 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. These steps should get her eating again. If not, try soaking the pellets in some garlic juice to stimulate the appetite and provide an immune system boost.
