Rainbow Bass are aggressive carnivores that are fiercely territorial and when hooked can get you down to your backing in seconds. They are found in rivers throughout Costa Rica and most notably Lake Arenal. They have a reputation of being excellent table fare. The world record is 12lbs 9 oz. They are not actually a bass but like the Peacock Bass they are actually a member of what is known as the cichlid family. They eat primarily smaller fish and frogs. Pronounced forehead bump. Their fins typically showcase a bluish-green color, which when all put together makes it easy to how it earned its name. Armed with a mouth full of imposing teeth, guapote earned their ‘bass’ moniker due to the way they are fished.
