2. Bubble Machines

Bubble Machines

Bubble machines will make a great addition to any themed aquarium, but a mermaid aquarium would be incomplete without one. A bubble machine in the shape of an old chest, drowned barrel, or something similar will create a great environment and add depth to the aquarium. It is also beneficial for the fish. A bubble machine provides the right amount of oxygen that a fish might need. Avid hobbyists recommend that in any densely populated aquarium, a bubble machine is vital. Just be sure to check your device beforehand to ensure that the flow is enough for the fish to bear.


3. Mermaid Statue

This is a no-brainer in a mermaid-themed aquarium. A mermaid statue will provide the finishing touch to your fish tank. It will also mark the aquarium as a mermaid-themed aquarium if that wasn’t clear enough before. A mermaid statue will provide character to the whole fish tank and add a backstory to your entire aquarium. One thing to note is that you need to make sure that it is purpose-built for a fish tank before purchasing one. It shouldn’t have any sharp edges, or that might end up injuring the fish in your tank.



4. Ruins

If you are planning on making a mermaid-themed fish tank, ruins will be a perfect addition. They act as excellent hiding and resting places for your fish. Aquarium hobbyists recommend that fish need a resting or hiding place. Otherwise, they become stressed and overwhelmed, which might cause their deaths. Not only ruin an excellent hiding place, but they also provide a unique look to your overall aquarium. Before buying ruins, you should make sure that they are adequately quarantined and sanitized first. Otherwise, bacteria can enter the tank, making it unsafe for the residing fish. You should also make sure that there aren’t any jagged edges on the fish tank, or else the fish might end up hurting themselves.
