Silver Dollar Fish

About The Fish

Silver dollar is a common name given to a number of species of Metynnis, a tropical fish belonging to the Characidae family which is closely related to piranha and pacu. Originating in the Tapajós River basin in South America

Description

round-shaped silver fish with slight red-tinged anal fin is mostly found in tanks kept by fish-keeping hobbyists. It will grow to a maximum length of 14 centimeters (5.5 inches).

Behavior 

The silver dollar is a peaceful schooling species that spends most of its time in the mid- to upper-level of the water. Its maximum lifespan is more than 10 years. A chin-layer, the adult fish will spawn around 2,000 eggs. This breeding occurs in soft, warm water in low light. The silver dollar is listed as semi-aggressive but it is very mellow like the pacu. These fish can be kept in community tanks with fish that can't fit in their mouths, so don't put a full-grown silver dollar with neon tetras and guppies. These fish can also be kept with larger fish like oscars, pikes, and larger catfish when full grown.

PH And Temperature 

Silver dollars natively live in a tropical climate in the sides of weedy rivers. They prefer water with a pH of 5–7, a water hardness of up to 15 dGH, and an ideal temperature range of 24–28 °C (75–82 °F) 

Tank Size 

Silver Dollars Grows fast so they like larg spaces to swimm so tanks with 20 gallon or larger would be better 

Diet

Their diet is almost exclusively vegetarian and in captivity they will often eat all the plants in a tank. They will also eat worms and small insects.
