How deep can MTS dig?

[Mindelo]

i have been planning a dirted tank, i'm fond of diversity, and snail multiplying fast does not bother me
however i'm worried about how deep can MTS dig, and if this could lead to having dirt on my water column
should i be worrying about this, or it is nothing to take into consideration?

ps: the dirt will be capped with sand, not yet sure of the sizes

the MTS will most likely dig into the dirt unless you had a *super* deep (4-5 in). I'd avoid them if you can.

They can dig to the bottom but it's not like they're scattering dirt everywhere like a dog or something, it'll more likely just blur the line between sand and dirt a bit. The sand might start looking dirty after a long time but I think they will do more good than harm if any.
