Is my p. boreus gravid or just obese and/or premolt.

I've had "Sreven" for a few months now and he's always been fat. This picture is from last month and he's only gotten fatter since. I've always suspected he was a she and he seems to be adult size for his species (he's a wild caught, so no idea of his age/history). Could he be pregnant? Or am I just overfeeding him?

*Steven, not Sreven.

I'll try to get a picture. She's really huge right now.

I take it you've determined she's a female? If so I think there's a pretty good chance she's gravid.

I'm fairly certain Steven is female, sadly neither my eyes nor my camera are good enough to get a pectine count, she's just a weeny thing, but I've since caught two other p. boreus (I'm fairly certain they are p. boreus as well, or a similar species) and comparatively, Steven's pectines are smaller, especially compared to this fellow:



behaviorally, I've seen Steven "stilting" over the last few days, sticking tail end high in the air and just sort of stretching it up. I've read that that's a sign of impending birth. Steven's also not eaten in a while, normally pigs out, so I'm hoping that if she is gravid, the babies come soon.
