Sand capped soil, corydoras?

[Tamitha]

Anyone have experience with a nice sized school of corydoras in a dirted capped with sand tank? I'm wondering if they will cause too much of a disturbance in the sand cap. Also, the tank in question has many plants like val and lilies covering the surface, will this affect the corys ability to dash to the surface for air?

I was wondering same thing but for kuhlis

I already have 5 kuhli in that tank with no problems but the larger body mass of the corys has me wondering. 
 

Thank you for the lily info!!

I have not kept corys so take what I say with a grain of sand, pun intended.

 

I believe they will sift through sand but are not huge diggers and substrate movers like African cichlids and some other fish species. A sand cap for dirt should be at least 1 inch, closer to 2 inches of sand which is doubtful they will fully disturb. I would think you most likely wouldn't have an issue.
