I don't usually get active in this area, but the "small loaches" intrigued me as I've kept some small ones years ago, so I may have some suggestions.
Botia sidthimunki (commonly called dwarf loach) are fascinating fish. Must be kept in a group as they shoal. They are a maximum 2.5 inches and quite active, closer to cory behaviour than most loaches. Don't know how well they control snails though.
There's Botia hora [seems the name has changed to Yasuhikotakia morleti] which is 4 inches max, and a noted snail eater. Kept in a shoal of 5+ they are less troublesome. Reported to be "feisty" to smaller fish particularly bottom dwellers. I had a couple that didn't cause trouble, maybe just lucky.
And there's Botia striata, a very beautiful loach, also 4 inches. Peaceful (moreso than others) and good at snail control. Best in a shoal.
Photos of these species attached, and here's a link to a loach site that may provide other info: Loaches Online - Community Edition — Loaches Online
Re the feeding, Twistermom has a method similar to mine; I use a piece (about 20 inches) of hard tubing with a 30 inch piece of the soft airline tubing attached. I carefully suck up a very small portion of thawed frozen foods like bloodworms using the hard tube end and can then direct them anywhere including at the bottom. Put the cube of frozen food in a dish of warm water to completely thaw first. Excellent way to get food to the bottom fish.
Last comment is on the fish per gallon issue. A sensible guide for beginners, but SinCrisis you're not that, so ignore it. Tanks can be heavily stocked provided the aquarist is rigorous in regular maintainance (especially weekly partial water changes of 40-50%) and the fish are compatible--which means share the relatively same water requirements and have compatible behaviours. Both these things reduce stress, and fish can be more numerous as long as they are comfortable and not stressed out by having to adjust internally to different water parameters, sudden changes, poor water quality, or unsuitable tankmates. I could cite several authorities who recommend 130+ smallish (shoaling characins, etc) fish in a 40g tank, and I have no problem with this number in my 70g and 90g tanks. But you need to know what you're doing and what the fish require. I do not stray from their preferred habitat when it comes to the water (hardness, pH, temp, and lots of plants).
