Do Channa micropeltes adults dig through the substrate?

[Naos1984]

I'm planning on doing a dwarf sagittaria and sagittaria broadleaf carpet on my next project and I wonder if it's worth the effort. Will adult Channa micropeltes dig? Say 30" big? I'm planning a 2-3" thickness for sand supported by ferts for the sagittaria. If that does not work, garden soil and laterite topped with sand is the alternative, again with ferts. I'll let the sagittaria settle for about 3 months before adding the fish. Thanks in advance!
