Man, maybe I have been overfeeding as well

( apparently that can also cause fin/tail rot? ) I have Atisons Betta Pro the tiniest little pellets the size of a poppy seed. He get 5-6 twice a day?? Yikes! The little tub they sent 2.65 oz would feed 100 fish 100 weeks!!
I started with hikari Betta Gold, but it was much larger, and really did expand!
His treat is fd bloodworms ( yummy) a couple times a week ( in lieu of pellets). Also pea treat - he gobbled that up too....has me thinking now....I think I best cut back.
