Well, the fish is Pseudacanthicus genus for sure. However, I don't think it is L114, the lack of patterns on the head tends to point this as L024. Maybe a better side shot show the entire body would clear things up abit.
After going through the process of elimination on all the Pseudacanthicus genus, I am starting to think it is L600. It is not L24, not L25, not L273, and most likely not L114.
Here is a link to the youtube video of another L600 that looks very much like yours.
after watching the above vid... im now leaning towards male L600... L114 and L600 are very similar and its really only the head pattern thats different....
either way you have a nice fish... im jealous <3<3<3 in a good way off course :thumbup:
