Well, yoyos "should" get to at least 4 inches in a year & up to 5-6" eventually, not at all slow growers. What kind of snails? Many smaller loaches (sids & striatas) can handle pond (bladder) & ramshorns & are "loach candy" for many species. Sids & zebras can eat both, but may need a few crushed snails to get the idea, both are easily "smooshed" against the glass so they get the idea. It's when you get to MTS (trumpet snail control) that the smaller loaches may not be able to eat them IME. MTS have a trap door covering that smaller loaches can't open. There's always the "bait & remove" with romaine or zucchini for all snails...& many loaches love those veggies, too.
Sids & zebras were always plant safe for me unlike their bigger bretheren..with regard to swords & crypts especially, U-shaped holes are signs of loachy damage...feeding romaine & zucchini vastly reduced plant damage...plus snail snacks...looks like a balanced diet to me, lol...veg & protein.
Back on my bandwagon, loaches are very social, get more or rehome them!!
