Nice, gals looks beautiful. My crowntail female was same way in terms of thinking she would soon pass. She was the last one left on the shelf at Petco in the CT female section. When I first peered through her cup she became very nervous and was darting around smashing her snout against the cup from one end to the other, probably why no one wanted her. Took a chance and decided to buy her.
When she was placed in the 15 for the first day or so I didn't think she would make it as she was very skittish, any little thing startled her to the point where she would fly into gravel, sides, ornaments, etc.
At present she has outgrown her nervousness and has become the Alpha female in my setup.
