What is the Best Substrate for Rainbow Sharks?


For Rainbow Sharks, a suitable substrate choice is fine gravel or sand. These active fish like to have a soft substrate that they can forage in without hurting themselves. Sand is particularly good because it’s very soft and won’t scratch the shark’s skin as they swim close to the bottom or search for food.

When picking the substrate for your Rainbow Shark, it’s also a good idea to think about the color. Rainbow Sharks are colorful fish, and choosing a darker substrate can help their colors stand out more. Plus, they like to have hiding places, so adding some larger rocks or decorations on top of the substrate can make them feel safe and secure in their home.
