I think they are 3-4 months old (they're about 3.5 inches body length). They've definitely grown since I got them, and have little tummies now, too. Here are some photos I took yesterday while they were eating a bloodworm snack. They now get their main dinner (Repashy freshwater meat pie) from my fingers (which is pretty cool), then munch on bloodworm snacks for a bit. They're very active, and always hunting, but with those bellies I don't believe they're starving. They've been swimming a lot lately, too. Abe Sapien is the leucistic, Nessie Goldenhair is the golden albino. Nessie is developing a lot of those iridescent spots lately, and in certain lights they really flash.
