Ray, your fish are most likely not spec. Ampah. The male you show us is too colourful; the reddish tone in the caudal is typical for filamentosus. The spec. Ampah looks somewhat like “black and white” with some brown bands in the dorsal and anal. And the black bands are rather clearly marked. Some have extended filaments, too, others not. All females of filamentosus have smaller filaments than the males, but they have.
The relationship of Ampah to filamentosus is clearly to be seen. The only question is: Is Ampah a separate species or is it a less colourful form of filamentosus? The classical location of filamentosus is about 200 km south, but it is most likely to extend far more north.
