lol well today my betta died and when i took him out one side of his stomach was green and the other was light blackish and it was scary??!!? ive never had this happen beforeany idea what this is? I fed mine betta pellets
If he was 2 year olds he was probably old. Sadly most bettas you get in pet stores are already 6 months to a year old and with a life expectancy of 3 years that's well... pretty much it.
