love those first 2 then that first baby
never really caught the fever for them full scale yet i have had a few over the years started with a red knee then got a green bottle blue mine didn't have the markings on the back like yours but mine had a Lil brighter blue. now got a salmon pink bird eater (supposedly the worlds fastest grower from what I've read about them but that one of your there seems to of blown mine away in growth (or at least thats how it looks from the pix mine when got it in march was a sling now the size of my hand) the shop i got her from got one 2 months later and it is almost as small as it was when they got it.(love the way mine grows it literally has doubled in size after it sheds
also from what i noticed about mine is bigger cages stress it out massively almost had it starve to death on me when i tried to put it in a 10 gallon cage was in it almost a month and in that time always had to pick out dead uneaten crickets same amount i put in. put it back in it's old small tank and it took food right soon as they hit the floor for the biggest part it caught one as it was falling in it's cage could tell it was super hungry it had 1 cricket on each fang and trying to grab more
