I have a few neon tetras mixed with some guppies. They appear to get
along during the day, but I always seem to lose one after I turn off the
lights and check on them the following morning. Are the tetras naturally
weak? The guy at the LFS told me that tetras have the highest death rate
at the fish store and was trying to convince me not to buy them.

Neons are bred in their millions in ponds in places like Singapore.
There is very little quality control. How long has your tank been set
up? What are your water parameters like, pH, GH, KH, NH3, NO2, NO3? Bear
in mind that guppies naturally come from slightly alkaline, hard water
while neons come from acid, very soft water. While both will exist in
different conditions it is hard to find an optimum for both species.

BTW can you turn off MIME/html on your newsreader and just use plain
text please? I have to reformat your post in order to make it
presentable.
