If you have a fish tank, you don’t just want a boring glass bowl filled with water and a little fish swimming in it; you should dive in and get it looking exciting! Aquarium ornaments are a great way to spice up your fish tank. Some folks even believe that the little ornaments you see in there aid in your fish’s overall health and stimulate their brain and other senses. Here are some great aquarium ornaments we recommend.

Purchasing Fish Tank Ornaments

The right fish tank ornaments will depend on your fish tank and the style you are trying to achieve. Look into these factors before deciding:

  • Size: You want to make sure the ornament you choose actually fits in your fish tank! Choose ornaments that are proportional to the tank size.
  • Health Benefits: Some natural ornaments are designed to help balance the pH level in your water and are thought to promote fish health.
  • Hideouts: Many fish like hiding under accessories in their tank, so look for ornaments that have good spaces for them to tuck themselves away.
  • Submersible: Unless you want a floating ornament, make sure they are heavy enough to sink or can be held down to stay beneath the water.
  • Fresh vs. Saltwater: Some ornaments are only safe for one type of water or the other, while some are safe for both. Make sure your ornament is safe for your water before you purchase.
