H. cinerea suddenly skinny, related to humidity?

[Gentlemangorath]

So I was feeding my H. cinerea, and one of my two, Verde, had already eaten about four crickets, when I noticed that he seemed extremely skinny on one side. I had noticed this earlier as well during the day, while he was clinging to the top of the background right next to the lamp. When I sprayed the tank a bit (with a portion of it splashing onto him) he seemed to get that stomach mass back, both before and now. He seems ok afterward, so I can't help but wonder what's caused this. I'm including a picture to make it easier to know what I'm talking about (his eye looks cloudy, but that's just the flash reflecting back).

Can you post another pic of him from the top?

Well I can get another pic, but he looks fine now*, so that picture from the top would look fine compared to when this was taken. It makes me wonder if it was just a humidity thing, because it was low when I had taken a look inside the tank tonight (and earlier he was literally under the light). He's still nice and active though, both of them actually just tried to catch water as I sprayed into the tank, and the Boom's movement provoked Verde to jump at him/her. I hope they're ok, he literally just jumped at him and fell down into the water dish >_<. They seem fine, but gah, that was reckless.

Image of him from above, even showing the same side, which does not look the same as it did during the above photo.
