Sand, Gravel or Aqua Soil? Choosing the Right Substrate

Did you choose the stuff on the bottom of your tank by colour? Most of us did, but your substrate affects your water chemistry, your plants, and whether fish like corydoras and eartheaters can feed the way they're built to.

This episode compares gravel, sand, aqua soil, crushed coral, dirted tanks and bare-bottom tanks, matches each to the fish and shrimp that suit it, and works through some of the hobby's longest-running substrate debates.

💬 Join the conversation: Are you a sand, gravel or aqua soil keeper, and have you ever switched and noticed a difference in your fish? Share your story in a review or find us on social media and tell us.
