how much should i feed a 3.7 inch giant betta?

[homegrown terror]

....and should i possibly have him on cichlid pellets instead of betta pellets due to his size?

I find that my huge girls (just over 2 inches in body at 10 months) can eat regular fish food (New life spectrum regular formula) since the Betta formula is too small I feed them as much as they can eat. Also give them a variety... I feed frozen mysis, which everyone loves - and the bigger pieces to to the giants.
You can use whatever pellets you like, as long as they are good for them and they can still eat it. :)
