Just for reference, here is a list of some fish that will work well with most snails.
Loaches
Hillstream loaches
Kuhli loaches
Both work well with snails although the kuhlis may just make a meal out of snails smaller than their mouths. Several other species especially those of botiine genus tend to prey on snails. Believe it or not, invertebrates are their primary diet so it is not surprising to see them attempting to pry off the snails to eat them.
Cypriniformes
Harlequin rasboras (Trigonostigma heteromorpha)
Hengeli rasboras (Trigonostigma hengeli)
Espei rasboras (Trigonostigma espei)
White cloud mountain minnows
Celestial pearl danios
Rasbora boraptensis
Boraras maculatus
Boraras merah
Boraras brigittae
Siamese Algae Eaters (Crossocheilus siamensis)
Garra flavatra
Garra cambodgiensis
Garra taeniata
Anabantids
Honey gouramis
Sparkling gouramis
Licorice gouramis
Chocolate gouramis
Samurai gouramis
Pearl gouramis
The only issue is most species mentioned above prefer acidic waters so I am sure shell erosion would be a problem there although these fish won't bother them in any way possible.
Catfish (aside from corydoras and plecos)
Hara hara
Glass catfish
Characins
Black Neon Tetra(Hyphessobrycon herbertaxelrodi)
Black Phantom Tetra(Megalamphodus megalopterus)
Black Skirt Tetra(Gymnocorymbus ternetzi)
Bleeding Heart Tetra(Hyphessobrycon erythrostigma)
Cardinal Tetra(Cheirodon axelrodi)
Columbian Tetra (Hyphessobrycon columbianus)
Diamond Tetra(Moenkhausia pittieri)
Ember Tetra (Hyphessobrycon amandae)
Emperor Tetra(Nematobrycon palmeri)
Flame Tetra(Hyphessobrycon flammeus)
Glass Bloodfin(Prionobrama filigera)
Glowlight Tetra(Hemigrammus eryhthrozonus)
Green Fire Tetra (Aphyocharax rathbuni)
Green Neon Tetra (Paracheirodon simulans)
Head-and-Tail-Light(Hemigrammus ocellifer)
Jewel Tetra(Hyphessobrycon callistus)
Kerri Tetra(Inpaichthys kerri)
Lemon Tetra(Hyphessobrycon pulchripinnis)
Loreto tetra(Hyphessobrycon peruvianus)
Neon Tetra(Paracheirodon innesi)
Penguin tetra(Thayeria boehlkei)
Red-eye Tetra(Moenkhausia sanctaefilomenae)
Red Phantom Tetra(Hyphessobrycon sweglesi)
Rosy Tetra(Hyphessobrycon bentosi)
Rummy-Nose Tetra(Hemigrammus bleheri)
Rummy-Nose Tetra(Hemigrammus rhodostomus)
Rummy-Nose Tetra(Petitella georgiae)
Silver-tipped Tetra(Hasemania nana)
X-ray Tetra(Pristella maxillaris)
Pencilfish (all species)
Hatchetfish (all species)
Cichlids
This seems a hit or miss. The following listed are possible but don't keep your hopes up they will thrive together.
Discus
Blue rams
Bolivian rams
Apistogrammas
Keyholes
Livebearers (not all will work)
Guppies
Platies
Swordtails
Mollies
Others
Rainbowfish
