I think you should definitely put in some Wabeen, they look very interesting. From what I can tell you are referring to Hoplerythrinus cinereus. These are actually a kind of wolf fish rather than a snakehead (snakeheads are native to Asia).
I couldn't come up with a photo of H. cinereus, but this is of a different Hoplerythrinus. Is it similar to the Waubeen you have in Trinidad?
umm no it is not similar at all ill see if i can find a picture of one but i was fishing in a river and left 2 of the mountain wabeen with a string threw their gills on the hot sand when i returne 2 hours later and threw them into the water they "came back to life so to speak" and ill do some research and see if either peacock bass or vieja can be obtained in trinidad
what u have there in your picture is what we call wabeen what i have in the picture is a mountain wabeen but i will eventually get some good shots of a mountain wabeen so that someone can identify its true name
