Yellow-Fin Grouper

The Yellow-Fin Grouper is a large and strikingly patterned Caribbean grouper recognized by its distinctive yellow-tipped pectoral fins and a body covered in dark oval spots and blotches set against a variable background that ranges from olive-green to bright red. This color variability between individuals and even within the same fish over time makes it one of the more visually dynamic grouper species.

In the wild, Yellow-Fin Groupers are common inhabitants of coral reefs throughout the Caribbean and Western Atlantic, typically found at depths of 2 to 45 meters. They are powerful ambush predators that feed primarily on fish, particularly reef species like parrotfish and wrasses. This species is notable for being one of several Caribbean groupers associated with ciguatera toxin, which accumulates through the food chain.

With an adult size approaching 36 inches, the Yellow-Fin Grouper requires a very large aquarium of at least 400 gallons. While hardy in captivity and willing to accept a wide range of frozen foods, this species is only practical for aquarists with the facilities to handle a large predatory fish. Its impressive coloration and bold personality make it a worthwhile addition to appropriately sized FOWLR systems.
