A. avic paralyzed after molt!

Yes, I agree, this may be severe dehydration. Hang the front end of the tarantula in a water bowl. It needs to drink. Wet paper towel does nothing except breed bacteria.

 

Tarantulas rarely drown. Just make sure its mouth is submerged but its book lungs are out of the water

 

He is dehydrated. Please put his mouth into a water bowl before hes gonna for good

 

Agreed, just put his mouth in the water and leave him there for a while or until he moves out himself. It's all you can do really.

 

Tarantulas don't breathe through their mouths, so you can safety submerge the mouth. The book lungs are on the abdomen (the main body bit at the back). So stick the front in the water and keep the back out of the water.

 

Completely wet - all over? I really hope you just put his mouthparts in the water, and not the entire spider! Tarantulas rarely drown - but if you submerged the underside of his abdomen (which is where his book lungs are located) and he's too weak to get out, that's exactly what you might have done.

 

Sorry to hear that. Sometimes a molt is just too stressful on their bodies. It could have been a lot of things that caused this. Either he was dehydrated and never drank any water in his premolt, possibly a feeder insect could have had something toxic in it's stomach when your T. ate it (such as a pesticide or Styrofoam which they have been known to eat) or there was a problem in his molt itself.
Unfortunately you may never know. I'd just recommend that you focus on your other T.s and make sure that their enclosures are maintained with a water dish of some kind in them, especially if you notice that they are in premolt.

 

Was its water dish full all throughout it's premolt? My A. Avic is a drinking machine in premolt! I give her a dish and pipette her web with droplets and she'll drink it right in front of me if shes in premolt. It's hard to say in your case if it was dehydration, but I'm definitely leaning more towards that, if there was no chance of pesticides.

 

This isn't proof your T wasn't exposed to toxins. We have people who had Ts in the same room, exposed to toxins, some died, the others didn't. Until you test for toxins (assuming there was something in the air) you won't know.
