These seem identical to the six i purchased recently from my LFS in UK. I presumed them to be either p.opallios or p.sp Sentang. I would be grateful for a positive ID, and will post photos as and when the grow enough to show nuptial coloration. i originslly feared i had all females but two are now showing colour in their fins.
By all means please post some photos of your recent purchase. It would be great for comparison purposes. I received two additional species this morning in the mail. Both groups are quite small and immediately went into hiding. Perhaps with a little food in the coming days they will stay out long enough to examine them. I receive 6 P. Linkei and 6 P. opallios.
