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.
Tarpon
The tarpon is often called the 'Silver King' for its large mirror-like scales and acrobatic leaps. This ancient species has existed for over 100 million years and can breathe air using a modified swim bladder.
