I notice that male betta that I have had for 3 years is starting to become lethargic. When I come near the tank he still pokes out and sees what I am doing and he is eating just fine.
He just isn't swimming around as much as usually. His face is starting to turn grayish almost like a beard on him. Also his fins are starting to turn white a bit.
He just got upgraded from a 5 gallon to a 10 gallon. I keep up on weekly water changes.
I know I have had him for 3 years but could it be possibly he may be older? I got him at a local pet store where I seen that he was there for a good month before I took him and nursed him back to health.
