Feeding amount and sundry kinds of foods question

Hello all. I think I may be feeding my GF too little. I've been
feeding him/her the same amount for quite some time - but he's grown
SO much (6.25 inches from nose to end of tail fin). I know there is a
guideline - all your GF can get in his mouth in one minute three times
a day? Is that right? Is ok to feed him a bit more if I know its not
overloading the tank? (its 60 gallons). I want to make sure he is
getting the proper nutrution.

I have been feeding him a variety of fresh stuff like banannas,
cantalope, blanched peas, and sometimes pasta. Im sure this is good -
but im gonna run it my you guys anway.

DROPSY UPDATE: As you all know - i've been haveing problems with my
GF having popeye and being swollen (no pine cone). He's doing much
better now - one eye is still wonky but he is RAVENOUS and has less
red spots.
