You made some good pictures. I just recognised the other topic.
If these fishes are P. sumatranus related, they are almost adult. Young P. sumatranus don´t really have color. They are more like black and brown dotted.
We can imagine the black dot in the dorsal fin. But in some photos it is missing. Maybe you have individual fish, or a differnt photo situation?
For me the photos in the other topic are interesting. It seems that the ventral fins and the gill cover are shinig cyan. That would be really differnt.
Nice fish!
