I am getting 3 ghost shrimp tomorrow. I'm newish with these. I have a 5 gallon tank with a betta. (I can have 3 shrimp and a betta in 5 gallons, right?) I feed my Betta and he eats up every ounce of food very quickly so there isn't any extra for the shrimp to eat. My tank stays very clean. Not much to eat there either. I used to feed my old ghost shrimp API Bottom Feeder Shrimp Food. They really loved that. I had two and fed them like 2 balls every other day. What is the best fits for them? How much should I feed 3 shrimp? Thanks!
