Keep in mind - this snail just looks like a regular 'pest' snail. But bear in mind it's there for a reason - you are overfeeding! Cut down the feeding instead of getting the loaches. These particular snails (I would argue!) are actually pretty useful - they don't eat plants and consume a lot of excess food which could otherwise be more harmful for your tank.
Here's a snippet I wrote in a pinned thread in this forum- which you might find useful:

The snails are there - not because they eat fish mess (it has low energy value as well as probably not tasting nice), they are there because there is excess food for them. Perhaps you are overfeeding your tank - cut back the feeding to every other day and reduce the amount you feed to your fish - they should be furious at the surface fighting for food everytime you feed them not lounging about in the middle of the tank and waiting for it to sink down to them and looking bloated. Cutting back feeding will also solve any algae problems you are likely to be suffering.
So the snail population will decrease over time - not because snails die off and pollute the tank, but because - well yes they will die over time but the fact is the food is no longer in great excess and so they don't rapidly multiply in a period of relative "snail boom".
To help them on their way you can manually remove them, there are many "methods" for making it easy to remove vast amounts of snails but unless you are SERIOUSLY overun with pest snails I have found them to vary in success never the less I will list them later. One solution is to pick the snails off in the tank - this is time consuming you drop them and they then lurk in the gravel, a modified solution to this is crushing them when they are in the tank instead of taking them out - i do not know a single fish which will not eat squashed snail! They make a sort of crunch - perhaps pest snail squashing isn't for everyone though.
The two main methods I hear as the "miracle cure" may work for you, but didn't for me.
1) Anchor a piece of lettuce under something, leave it overnight and when you turn on the lights the next morning it should be covered. Just pitch them in the trash. Simple and completelty safe.
The second method varies only in that it uses courgette /zucchini (I believe you Americans call it that?) inside a glass, and feeding the caught snails to a tank of puffers or clown loaches instead of throwing it into the trash.
