To the best of my knowledge these could well be p. gunawani.
(So I did buy six)
Its always hard to tell with scared fish in a bright sales tank, but they have a special ‘body or fin – shape’ – they have the blue lines, they do have a faint brownish/reddish colour in the fins… so ….
edit : they are not probably Gunawani 😉 unfortunately my id skills are inadequite
