tiger shovelnose catfish

  1. Sand Vs Gravel

    Freshwater Aquarium Equipment
    I've been running my 3 tanks (30G, 75G, 160G) with gravel and I recently purchased a tiger shovelnose catfish, before reading that they do better with sand or no substrate due to them potentially eating the gravel and not being able to digest it. Will this hurt/kill the fish? Should I change...
