These creatures appear to live in the gravel during daylight, and emerge during the dark. There at least 100 in a 45 gallon tank. What are they?

They almost look like rabbit snails, but those have never been introduced into the tank. I had to turn the light on in the middle of the night for these pics.
 
Definitely snails of sorts - they can come in on plants, rocks, anything that has been in another aquarium really. I dip all my plants with some potassium permangenate for a bit before adding to tanks.
 
They are live bearing cone snails,(AKA trumpet snail, MTS etc etc ) and yes they usually spend day light hours hidden in, and rummaging thru the substrate,
One of their attributes is that their constant rummaging keeps the substrate loose , from compacting, and from going anaerobic.

although they are slow growers, they can reach about an inch

Once established in a tank they can be difficult to get rid of, if that is the desire.

Assassin snails work.
I found the most effective biological control was using the Madagascan snail eating cichlids of the genus Paretroplus.
They can crush young snails, but have can opener like teeth that extract even the large tough shelled adult snails.

Some of these fish get large, 15" so not recommended unless the tank is adequate.
I had a large one I would shuttle between 20 tanks, that could rid a tank inundated with snails, in about 24 hours..

They are considered invasive species in some places , so care should be taken not to release the i natural waters.

I was going to say if I was in your position I might set up another tank and get a puffer. Because I like puffers but feeding them sucks w/o another tank with a self sustaining population of snails. Your loach should be pleased.
 
MTS as others have said. They are great for cleanup, but are annoying in big numbers.
Loaches and other snail eaters are the best bet for removal.
 
Trumpet snails .I alway kept a few in my overflows or sumps to help with clean up. They are nigh indestructible., but a few botias (including clownloaches) will keep them in check
