Best Fish to Eat Snails in a Planted Tank
My 40g tall tank is starting to settle in nicely. The initial diatom bloom has gone, and algae is now starting to settle down as the tank is balancing out. But, I have snails which came in with one of the plant orders (I won't mention the vendor, but I'm a little irritated about that). Anyway, where they came from doesn't really matter at this point. As long as there were only a few, I didn't really mind, but at this point I've got far too many. So many that when I drop a wafer in for the Corydoras, the nearby snails are all over it before the Corys get a chance, so its time to do something about it...
I'm not really a fan of any chemical snail remedies, so I'm looking for natural solutions. In previous tanks, I've tried Clown loaches for snails. I was never convinced they were really eating the snails, but they certainly did a good job of disturbing the plants as they rummage around. Also, I've never kept loaches with shrimp before, and I'm a little worried they'd go for the shrimp too.
Does anybody have any experience of what fish are actually effective for dealing with snails, and are suitable for a planted tank? I don't really want anything that will get too big, the tank is only 20" by 18", and with 3 Corydoras Julii, I think the bottom is already pretty well populated (another reason I'm wary of Clown loaches, I know how social they are, and I don't really think I have room for them).
