I bought this wolf fish from a good friend of mine and he claims that it is a hoplias lacerdae but I’m not so sure about it, so I need a few guidance and Id from the experts. And the link is the under jaw of the fish hope it helps the identification
Easiest way is that the folds are parallel for lacardae. Like below. The pic below doesn’t show it well but there are 6 pores there to count. The one you posted has 4 showing. Plus pattern on ur fish’s body isn’t right for lacardae.
