I'm a high school student and I need help stocking a tank. We need to make money and I was thinking of putting something up saying feed **** for 1$ like feeding piranhas and tiger barbs something. But I was wondering if there was a reasonable fish you could hand feed. Preferably we'll known and big and enticing to people. Maybe some kind of catfish or American cichlid. But any ideas to make money except for breeding would be appreciated.
