I have a bunch of MTS in my 10G livebearer tank (with other snails and ghost shrimp)
The problem, is the gravel seems too large for them to dig effectively.
I watch them pretty often...
They act like cats.... if anyone has ever seen a cat put their head in a box or paper bag and go to sleep, they apparently think they're hidden. The snails to the same thing. After a bit of struggling, they manage to get their front end under a large piece of gravel, and then just sit there.
I think the biggest ones do hide, but I have no idea if they're hiding in the gravel or just under plants. Seems like they like to squeeze under my dwarf baby tears like it's a blanket or something. I finally surrounded the baby tears with rocks so they will leave it...
The gravel is from wal-mart... so it's a little bit too big, even though the plants seem to be doing okay.
I'm planning on rearranging the tank soon- would it be stupid to replace the substrate with sand just to make the snails happy? Would it be unneccesary?
In my other tank (soil substrate) I added about an inch of sand over the already in-place one inch of gravel... So far, they've mixed the sand and gravel but the soil is staying there it should.
Should I add an inch or two of sand to the livebearer tank so the snails and shrimp can have their fun?
