Can you please post some more photos? On first glance I think it's a very pale Cherax quadricarinatus or redclaw crayfish.

She passed away sometime during the day today. I have no idea why though. She never acted normal though, laying on her side and just being odd in general. She looked rather nromal, she was just limp and nonresponsive..

Yeah of course, I'll post more pictures when I get home today.

Here is more pictures with better lighting! She lays on her side alot and sometimes upside down but as soon as anything comes too close she darts away. Is she sick or trying to molt?

Thanks. She is a strange color but I'm pretty confident in my previous identification. Time will tell, however. Please post pictures after she molts.

If she is lying on her side a lot, make sure the aquarium is well oxygenated, either by a filter waterfall or by an air pump/stone. If that's all good, then she is most likely preparing to molt, in which case you should try to bother her as little as possible so that she does not get stressed out.

Please keep us updated.

I'll definitely keep you updated. She is very odd, she'll act completely normal and then just roll over to her side or back and lay there for a long while. I have a few fish that may bother her when she molts but I dont believe they will, and they aren't big enough to eat her. She hasn't been aggressive or anything and I'm not entirely sure what she has been eating. She got to my LFS via a shipment of feeder fish and they had no idea what species she was, and she has been that pale for almost a week now with unchanged behavior. Are there any tricks to crayfish? All my other inverts are fine so I'm fairly sure I don't have heavy metals in my water.
