I have 6 Zebra Danios who are very busy. I feed them Tetra Tropical Flakes once a day and brine shrimp weekly. They turn into little basketballs when they eat the shrimp, they really love them. I feed them FBS for the protein content and the Tetra Flakes because they are tropical fish and I really have no idea what else to feed them. I have read about other fish keepers feeding other things and wondered what the advantages were, why they chose a particular food and where they purchase it. I haven't seen anything specific about feeding so I thought I would start the discussion.
