Our tiger salamander has been acting stragely: digging in the rocks at the bottom of the aquarium, moving slower and eating more. Could it be pregnant? and is there really any way to tell which is a male or female? We have two of them and are wondering if one may be pregnant. Also, is there a risk if the female is pregnant that the male could eat the eggs and/or larvae? Thank you!!

It's probably looking for a place to burrow and hunker down for the winter.
Tigers have not been bred in the US in captivity, nor do they breed in the fall. They also migrate back to their natal pond to deposit eggs.

This link will answer most of your questions. http://www.caudata.org/cc/species/Ambystoma/A_tigrinum.shtml
from your post, I would make sure you read the section on housing. Tigers require a soft substrate in which they can burrow, sounds like you may have a gravel substrate? There are no substantaited reports of tiger sallys breeding in captivity. With tigers your can normally determine the sex by the size of the cloaca, males having the larger cloaca than the females.

I agree with the posts from Kaysie and Chris. Be sure to read the page that Chris gave the link to.
At this time of year, it's normal for tiger sals to slow down a bit and "bulk up" a bit. It's even possible that your sal is developing eggs (becoming gravid). But it's virtually impossible that any eggs will be laid, this species just doesn't breed in aquariums. (There have been captive breedings, but only in large outdoor enclosures, never indoors.)
To re-iterate Chris's advice, tiger sals are best kept in a soil-type substrate (terrarium), rather than an aquarium with gravel. For ideas, see:
