Strawberry poison frog 110920?

Yeah, I think they are Imitating poison dart frogs.

Strawberry PAFs are incredibly variable - this is well within the range of their possibilities, which range from red to blue to green to spotted to stripey to plain to the classic 'red frog wearing jeans' look: CalPhotos

Looks like the Bastimentos form here.

@Maguari yes does look like the Bastimentos one as you say - thanks

@CheeseChameleon2007 I was going towards Imitating too, but think @Maguari may well be correct
