This latter shown fish is most likely a young ornaticauda-male in plain colours caused by that light conditions without any structure or cave. The white edges in the anal and dorsal and the type of marking in the caudal make this very probable. But this means that the names that are offered by this dealer are very accidentally and wrongly used (which is quite normal with Parosphromenus in trade). The females don’t have these markings. In display the fish has a completely different colouring that looks rather striking. There is a unique heads-up display dance.
Which was the name you were given? But your so-called “spec. Ampah” should look differently. And they have a completely different body-structure, I hope?
