Species Overview

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.

Peixe-leão-vermelho

The red lionfish is a venomous coral reef fish native to the Indo-Pacific. Its ornate, striped body and fan-like pectoral fins make it popular in aquariums, but it has become a destructive invasive species in the western Atlantic and Caribbean.
