This is my first post
I bought my betta when he was very very small 7 months ago which leads me to believe hes about 8 months old. I also bought a Betta kit with him small tank but he always seemed happy with it! I regularly change his water once a week sometimes sooner! and feed him Tetra's BettaMin Food. I am usually always around him if I'm not in class or at work and he's very energetic.
This past week I've noticed his gills has become alittle swollen and hes starting to loose colour
he's also sitting at the bottom of the tank in a vertical position and hasn't eaten in acouple days
I have a picture of him here, that i just took as you can see he's sitting upwards some one please help
