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.
Rainbow Trout
The rainbow trout is native to cold-water tributaries of the Pacific Ocean in Asia and North America. Widely introduced worldwide, it is prized by anglers for its acrobatic leaps and beautiful coloration.
