The G. pulchra is looking VERY female!! They are pretty obvious when they are males. And with the Larry it is hard for me to really see a good ventral shot with that pick. Nektu said he got a good look and is sure it is female. But since you already have a female if both look the same from a ventral view you should have 2 females. Roseas are notorious for going on very long fasts!!! Larry's abdomen looks good so I would not worry at all!!
