They're hardy, peaceful, and constantly on the move, making a lively school the perfect \"starter shoal\" for a new community tank or a great splash of motion in an established planted aquarium. Care level is beginner; temperament is peaceful (active but not aggressive).\u003c\/p\u003e\n  \u003cp\u003eLooking for more freshwater fish?
