Giant Silver Dollar Fish (Redhook)

The redhook silver dollar (Myloplus rubripinnis) is a tall, disc-shaped characin from the Amazon and Orinoco basins, bright silver with a distinctive red, hook-shaped anal fin that gives it its name. It is the largest of the silver dollars commonly sold and a genuinely impressive shoaling fish in a big tank, moving as a group in a way smaller schooling fish cannot match at that size.

Aquarium care

• Grows large, commonly 25 to 30 cm, and deep-bodied with it.
• Shoaling — keep five or more, or they become nervous and skittish.
• Needs a tall as well as long aquarium to accommodate the body shape.
• A committed herbivore. It will strip live plants, so plan for artificial planting or accept the loss.
• Feed vegetable-based foods, blanched vegetables and algae wafers alongside quality pellets.
• Easily startled — sudden movement near the tank can send the group into the glass.

They suit a large aquarium with other big, peaceful South American fish such as large catfish and calm cichlids. They are not a planted-tank fish, and they are far too large for a standard community. Keep the tank in a calm part of the room if you can.
