Perhaps this is gender, because the ones who are thinner tend to amplex the others. However, I'm a bit concerned with some that look slimmer. I tong feed them on a schedule regularly with gutloaded crickets, and have recently given some horned worms (soft moth larvae) as a dietary suppliment (along with the dustings, of course). Everyone is very active, darting around the tank and having HUGE appetites.
Should I be concerned or do you think it is simply physical gender differences?

I can/will post photos in the empty cleaning tank for some reference when my phone is properly charged
