How deep?

[My2heartboys]

I currently have a sand sifting snail and one of the fish that my kids are interested in is a watchman gobie. Knowing that these two have tendencies to dig into the substrate--how deep do I need to have it? Right now I have about a 2 inch depth.

2in is fine for a a watchman goby, the books say you want 3" for the burrowing Jawfish, so you are good where you are

Neither actually require sand; they just prefer to dig in it. Like Jiddy said, two inches is plenty.
