I generally feed my neons and guppies once a day, my problem is that I'm not sure my neons are getting enough to eat! I feed micro pellets and just enough for them all. I don't want to put more in because either the guppies will get too much, or the feisty neons will get too much. There is a few neons that look quite slender, they are not sick and are acting fine, just think they don't stand much of a chance at feeding time
