yeah from the pics I would say the carpintis is male, but if it has a dark dorsal spot that isnt showing up in the pics then yeah i would go with female, GT and Jag are def males and cant tell with the RD, you will need to vent that one to be sure (and might as well vent the carpintis as well while you're at it)
and just so you know, that blood parrot is going to get killed pretty quickly by those bruisers when they get larger (im surprised they havent already taken it out)
