Without aquarium decorations, your tank is just a bowl with fish in it. Decorations and backgrounds give it life and personality. With all the plants, rocks, and figurines to pick from, you can truly make your aquarium unique. If you are just starting out, you'll want to get a wide selection of unique items for your tank. Driftwood, plants, rocks, aquarium substrate, marbles, fish tank backgrounds and ornaments, Pet Mountain has everything you can think of for your aquarium. Some of the larger, saltwater or reef tanks have entire cities built at the bottom of their tanks! With the larger 100 gallon or bigger tanks, you can even put large rocks and coral in there to give it that ocean floor look.

For the brand new fish enthusiast, you can easily start small and just get a few plants and an ornament or two. Popular ones include the shipwreck and pirate with a pot of gold. Some people like to match the color of rock with the colors of the fish you have. There are all kinds of ideas you can use for your aquarium decorations.

Hi Erin,
Very generally, acrylic sealants can be used to coat an object to use in a tank. Using anything organic is risky though. Even a small crack or hole in the sealant will let water in over time and will get bigger and bigger. Most jaws that are sold in sea shell shops and as souvenirs have been bleached to make them whiter and adding them to an aquarium could release any chemicals they’ve soaked up into the water. Depending on the water parameters, they can also start to dissolve and release calcium into the water which would affect the pH and hardness. Other animals like starfish would almost certainly start to decompose once they get exposed to any moisture. A safer approach if you would like the look of saltwater animals in a freshwater tank would be to go with ornaments. We have some very realistic-looking and you may be able to find a resin shark jaw ornaments as well (we’ve carried some in the past that we’ve unfortunately since discontinued).
