4 pellets and 1 one bloodworm seems like plenty to me, if not a little too much. It is important that they get some protein so they start growing but remember not to overfeed them and accidentally cause any set backs from bloating or SBD. They sound really cute!!! =)
My Current bettas:
Sullivan- Orange rose tail halfmoon male
Daisy- Mustard Gas (black and yellow) veil tail female
Milton- Teal butterfly halfmoon male (mom's betta)
DFTBA to nerdfighters working to decrease world suck!
