Hey everyone a local store had some barracudas so I picked up 2 of them and they were only eating live fish. I put them in a 90gal they r currently 5inches was hoping having roseline sharks and a few other fish they would encourage them to eat what I'm feeding which is raw shrimp. It's been 2 weeks since they ate when I walk up to the tank they r definitely interested in food but once I throw the shrimp in they don't even try. Any tips to get these guys off love and onto raw shrimp??
