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.
Red Drum
The red drum, or redfish, is an iconic inshore game fish of the Atlantic and Gulf coasts. Identified by the distinctive black spot at the base of its tail, it feeds by tipping head-down in shallow water, exposing its copper-colored tail.
