Stoplight Parrotfish

(Scarus viride)

Scarus Parrotfish should only be added to very large aquariums with sufficient algae growth on the live rock. Ample cracks, crevices and caves should also be provided for hiding and grazing. Parrotfish will bite the live rock with the algae, consume the algae, and grind the rock with their plate like teeth in the back of their throat which produces sand. The sand is then deposited on the bottom of the ocean. Parrotfish need sufficient room for swimming and grazing on algae. House with other peaceful tank mates. Ensure a constant supply of algae based foods are available, supplementing with prepared algae based foods with Spirulina. Most Parrotfish will exhibit color differences between juveniles, females and males.

Stoplight Parrotfish are also sometimes known as the Red Belly or Parrot Chub. Uncommonly seen in the aquarium trade. Stoplight Parrotfish can range in color depending on their age or sex. Juveniles and young are generally brown with a red belly as they mature they turn a lovely green with yellow spots on their tail and caudal fin. Stoplight Parrotfish can grow to almost 15".

We recommend a minimum aquarium size of 150 gallons or larger for this species.
