what kind of food do sawfish eat?

  i inherited two sawfish from my uncle but i dont know what to feed them so please help
They eat squid, shrimps, small fish and crabs.
Sawfishes feed on small fishes and invertebrates that can be ingested whole through the mouth . They only feed on prey that can fit into their small mouths since they are unable to tear chunks off prey items with their toothy saw.
Big fish eat small fish ..... tuna.
