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.
Wahoo
The wahoo is one of the fastest fish in the ocean, capable of reaching speeds of 97 km/h. Its elongated, torpedo-shaped body and razor-sharp teeth make it an efficient pelagic predator found in tropical and subtropical waters worldwide.
