The baby pic you just posted does look like a
P. adspersus. Wish some scientist would complete a genetic DNA review of the whole genus and find out how many of it's species are true and if they are hybridizing. My Pixie "Duncan" shows both
P. adspersus and
P. edulis traits and got it as a full grown 3 in. male. Don't care the species really; but wish differentiating among them was more cut and dry
