Typical Asian import Platyrhincus (Oculatus?) 99.5% of these young off season fish are the same thing.... Dead give aways are 1. they will have a stupid made up common name and 2. the dark dorsal stripe will really only be present distinctly in these fish. If you look at the ventral fins they are also marked which will seperate these out from Shortnosed.. Longnosed look nothing like these fish..
There are only four species in Lepisosteus, it's really not as hard as it looks to ID them...
