If you use a sharp substrate for the aquarium, it may hurt the fish’s body while digging. You can see the scratches on the fish underneath. So you can use sand or Sharpless gravels for the fish tank.

How to reduce Digging holes
There are a lot of ways to reduce the fish’s habits from digging holes in the substrate. You can reduce the use below ideas.
#1 Make A Big Tank
You can set up a big tank for the fish. It will reduce the digging of holes for creating a burrow to hide. There will be a lot of space inside the tank with live plants. So the fishes can hide faster when they get attacked.
Try to feed them enough food otherwise, they may dig the holes for finding the food underneath the substrate.
A big fish tank will solve the major problems like stress, digging holes, and fish fighting between them. You can avoid these things using a big tank. Try to put small fish in the tank and avoid overcrowding.
#2 Use heavy rocks for fills bottom
You can use heavy rocks for filling the bottom of the tank, so the fish can’t dig the holes due to heavy rocks. Before adding heavy rocks, you need to use sand substrate in the tank bottom to prevent the glass from scratching.
#3 Provide Caves and places for hiding
Create caves and places for hiding. You can use decorative materials for creating a beautiful aqua environment and caves for hiding. So the fishes will not dig in the substrate for creating burrows to hide.
#4 Use bare bottom fish tank
You can use a bare-bottom fish tank to prevent the fish from digging holes. But bare bottom tanks are very hard to maintain because the waste will float on the bottom without hiding. When the fishes swim through the bottom, the waste will spread in the water.
The tank gets dirty faster and the fish will struggle due to the lack of oxygen in the tank. I’ll not recommend using bare bottom tanks for the fishes because the fishes need a good aquatic environment and substrate for resting.
#5 Reduce Stress
Another way to reduce the digging of holes is by reducing stress. The fishes will feel stressed when they get attacked by fishes. So you need to separate the fish into a new tank otherwise they may get stressed and lead to major health issues.
