You can still add a little soil to potted plants, then bury the pot in the sand/gravel and lay some flat rocks covering the pot around the plant so the fish cant dig it out.

Nah, I can't stand pots in the tank.  Don't know why, it just bugs me.  But if I can keep my cichlids from digging, I can do the same with the sunfish

Several other threads have discussed the merits of Walmart's Special Kitty cat litter. Being baked chunks, it settles into something denser than normal soil and withstands digging fish better. I keep Enneacanthus sunfish in it. It does cloud the water initially, especially since it will hold a significant amount of air following first wetting, which makes it much less dense at first. Erica posted a fairly detailed analysis showing its nutrient properties to be essentially the same as soil.
