Food and feeding

Red bay snook is definitely a predator and can swallow fish that are quite large. It will accept cichlid pellets and cichlid sticks, supplement the diet with meaty foods like chopped earth worms or feeder fish.


Central America; Red bay snook is found in Mexico, Guatemala, and Belize.


There are no visible differences between the sexes although it is believed that the males may grow slightly larger.


Red bay snooks are substrate spawners so provide some flat rocks or slate to act as spawning sites. The eggs will be a pinkly colour when laid and they should hatch after 3-4 days. A week later the fry should be free swimming and can be fed on newly hatched brine shrimp.


The expected life span for Petenia splendida is 10 years.
