I am looking into buying some snails for a 20 gal fish tank to help with the algae control. The fish I have now are:
1x Male Betta
2x Blue Painted Moons (Platies)
5x Peppered Corys
1x Clown Plecos
And I'm looking to add a few more critters like platies, tetras, rasboras and ghost shrimp. While I'm mainly looking for some Otocinclus Catfish, but since the places I buy them from are out, I would really like some advice on what would be the right snail to add.
I'm looking into buying some Nerita Snails, but right now my main concerns are making sure that the snails won't escape the tank, and since I have a pre-filter for my tank, that it won't eat the sponge and leave holes big enough to allow small fish and shrimp to get sucked up.
If anybody could provide some information on what snails would be best for beginners and less trouble, it would really be appreciated.
