Why not soak river mud/sludge in salt water for while and vice versa for Marsh mud?
Do it outside though as odors from mud/sludge may be very unpleasant.

I'm going to upload pics tonight. I have Play Sand in my mudskipper tank and they have a really nice long/deep hole they dug and it has not lost it's shape. They even made the entrance to the hole long where it's right on the waters edge. They also have a little whole they dug that hasn't lost any shape. They have been up for over a month now. I'll post pics tonight and show you. I think sand works just fine.![]()
