Native snails as substrate cleaners
Posted 01 February 2008 - 12:21 PM
I know snails are hosts for many fish parasites, but wouldn't snails from fish-free waters most likely be clean?

Some people have spoken very highly of native olive nerites. I'd love to try some myself but don't have a good (read: cheap) source.

I have tons of Malaysian Trumpet snails if you decide you want some. I will send you some for shipping cost.
Thanks, I may take you up on that. It'll be a few weeks before I set the tank up; I'll pm you then.

I have some native snails in my tanks. The dime-sized planorbids are excellent detritivores and sunfish fodder, but the big, conispiral lymnaeid pond snails are occasional plant eaters and lay enormous egg masses all over the tank. They aren't that bad, though.
A lot of the native snails can be big plant eaters, so people sometimes avoid them. The generic pond snail doesn't do too much damage in my tank, but they do leave a lot of egg masses on the walls. People like the Malaysian trumpet snails because they don't eat plants and are livebearing (no unsightly eggs). Plus, they really come out more at night, so are less conspicuous.
I'm also up to my eyeballs in Malaysian Trumpets. They are indeed livebearing, nocturnal, more or less inoffensive and useful aquarium subjects. They are also parthenogenetic and have an operculated shell that allows for excellent resistance to dessication. They are phenomenal invasives, and are doing a number on endemic snails in places like the Bonneville Basin. They can be schistosome vectors, too.
When I broke down my 55 gallon I let the substrate air dry, then dumped it into a sealed 5 gallon pail and left it on the porch for a full year. Frozen in the winter, 95* F in the summer, and bone dry. So I set a new tank up, and as soon as I got that stuff wet the MTS were out having a look around.
