Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Cherry Barb
The cherry barb is a small, colorful fish native to Sri Lanka's shaded forest streams. Males develop an intense cherry-red coloration during breeding. Listed as Vulnerable due to habitat loss and over-collection for the aquarium trade.
