Monoculus , kilberi, and pleiozona have the 3 prominent vertical bars, like yours .
But kelberi also has prominent spots on the pectoral and anal fins, so it probably isn't kelberi
pleiozoma sometimes has a 4th vertical bar, which can appear and disappear (can't tell by only 2 photos.
It also has a different amount of scales than the other 2, which "you" would need to count and compare with the scientific descriptions.(simple right?)
These difference also assume it is not a hybrid, which in these days of intended, or unintended, random crossings is problematic.
