Hey, I'm not really sure how much I should be feeding. I've read however much they'll eat in 3-5 minutes, so if he gobbles it up right away just keep dropping in more? that seems like a lot for such a small fish! but i don't want to starve him. I've gotten used to feeding tetras over the past few years. I've been feeding at 3 different times during the day, less on weekends. so far pellet, frozen blood worm, and small freeze dried shrimp.
