Yo, triggers arnet big fish eaters anyway. They are more crustaceans (hence the "beak") Heres a nifty little trick though. Go down to a beach or somewere near you, and grab some fiddler crabs from under rocks. Either that, or catch some freshwater crawfish. Freshwater crustaceans still contain the same amount of nutrients as saltwater ones do. If u thought is was fun watching it tear apart a goldfish, wait till u see it nail a live fiddler crab. You could probably also buy like cocktail shrimp (with the shell still on, uncooked) at the store and feed it one of those once a week. This is more natural for them, cuz they are more adept to eating crustaceans in the wild, with the occasional fishes. Im not saying that they DONT eat other fish, they just more likely nail shrimps and attack bivalves. And just cuz Im on a role here, the beaks are extended like that to grab shrimp in small spaces (kinda like a longnose hawk) and the "triggers" are for wedging themselves in between rocks to hide from other predators, which is also why they are so flat. So, if u see em hiding, they are just acting normally. Sorry, u didnt need that part, but I felt like saying it. SOO, if yer near the water, go grab some live crabs (smaller depending on the size of the trigger) and drop one in, grab some opocorn and soda, and enjoy!!!:hilarious
