Species Overview

Clownfish

The ocellaris clownfish is a protandrous sequential hermaphrodite that lives in a mutualistic relationship with sea anemones. Its mucus coating protects it from anemone stings. All individuals are born male and the dominant fish transitions to female.

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.
