The Blue Hook Metynnis, or simply blue hook, is a rare member of the silver dollar family. Wild-caught in Colombia, these fish are peaceful vegetarians and grow to 7 inches without eating the smaller neons schooling around them. These fish will also eat flake and pellet food, so they are a bit omnivorous.

Care Guide
Tank setup: Silver dollars are active schooling fish. Give them open swimming space, a tight lid and sturdy or artificial plants, since they eat soft plants.
Feeding: Feed a quality flake or pellet with vegetable content once or twice a day. They also enjoy vegetable foods like peas.
Tankmates: They are peaceful and get along with other medium to large fish such as larger tetras, plecos, parrots and peaceful cichlids.
Good to know: Blue hooks are named for the blue sheen and hooked fin on mature males.
