it's ok, i won't hate you forever for not choosing platies.
and about the food. my most active guy, Jasper, doesn't eat that much, i'll give him a pellet and then he'll swim away. but my other guy, Fredy, who is still active, just not as fast (tisk tisk), will eat 2 in the morning and then beg me for one a couple hours later. Then he gets two or three in the evening and he's perfectly fine..
I don't know if that information actually helped but, there you go anyways :)
