Dark Green Parrotfish
Sparisoma viride
A reef sculptor that literally chews coral into Caribbean sand.
About
The dark green parrotfish (Sparisoma viride) is one of those species that makes you rethink what a fish actually does in an ecosystem. Native to coral reefs across the Western Atlantic, from southern Florida and Bermuda down through the Caribbean to Brazil, this species spends its days grazing algae and biting chunks off live coral with a fused, beak-like set of teeth that never stop growing. That constant crunching produces a surprising amount of fine sediment, meaning this fish is a genuine contributor to the sandy beaches of the Caribbean. Juveniles tend to stay closer to seagrass beds and weedy shallows before moving onto the reef as they mature. Adults are typically found alone or in small groups and are strictly daytime fish, settling onto the bottom to sleep at night. In the aquarium, the labeled "beginner" care rating is a bit misleading. This fish gets large, needs a very spacious setup, and will make itself the dominant presence in any tank. It will hold its own against pushy tankmates rather than back down. Keeping one long-term also means accepting that it may graze on coral, so reef tanks are not a realistic option here.
