Hello everyone,
only for the sake of completeness I wanted to add some pictures of my harveyi to point out the differences between them and Omaha’s fish.
To me, the iridescent band in the unpaired fins of Omaha’s fish looks much cleaner and more consistent. In the harveyi it looks a bit “mottled” (esp. in the caudal fin).
The colour of the harveyi’s iridescent band is blue, but only in the anal fin while it turns to some sort of white in the caudal and the dorsal fin. This appears even slightly golden (due to the yellowish water?).
In my opinion, the harveyi also look more stout in general.
I think it’s a good idea to name your fish like you did (at least provisionally) and keep them seperate. Perhaps it is able to find out where they came from. …As far as I remember, there were P. bintan traded at that time in Germany. They were confirmed to be “real” bintan and available in several shops e.g. Tropicwater.
Furthermore good luck!
