Soil and Trumpet snails
Stephen Pushak answered Miles Morrissey and poised a question about
Malasian Trumpet snails and soil substrate saying he had heard that they
cause the soil to come to the surface. My 125g discus planted community was
set up "Ammano style". There is approximately 1" of peat/vermiculite/clay
covered with about 2" of fine gravel. (I forget the exact measurements,
they're at home in the fish journal) The only peat brought to the surface
came from my pulling up plants that didn't want to be uprooted. The fine
gravel did an excellent job holding down the soil and only 2-4 peat pieces
actually came up. Yes, there were some very fine particles released into
the water, but the filter removed them after a short amount of time.
So to the question - The trumpet snails seem to stay in the gravel and not
burrow down to the soil. I have never seen any in the soil level next to
the glass, but then I've never actually looked for them. They like to skim
over the gravel surface and when I clean the gravel, there are a lot on top.
They fall slower than the gravel so are easy to harvest. Anyone in the
Atlanta area can get a starting culture from me. For that matter, I'll be
glad to mail them if folks will pay the price of postage.
