Aquarium Rock Design Ideas

You can also use colorful stones and rocks to decorate your fish tank. Many aquarium decoration ideas use stones in naturally themed fish tanks. The most used rock decors are glass rock, river pebbles, and rainbow rock. You can also use natural stones that you find outdoors. Make sure that you boil them for about 3 hours to kill any harmful bacteria. Also, avoid sharp rocks like lace rock.

Shipwreck Aquarium Decor

Shipwreck decor is another unique fish tank idea if you want to go for an accurate underwater setup. Sunken ships not only add beauty to your tank but also provide hiding places for fish.

Bubble Makers & Air Stones

Bubble makers are one of those fish tank decoration ideas that not only intrigue fish but keep fish owners entertained as well. They can be relaxing to see. From a practical perspective, bubble makers are great for aquariums with lots of fish. It is because they help create more oxygen in the water, which is a must for fish.

Castle Aquarium Decoration

Medieval lovers will enjoy decoration ideas that add castles to the aquascape. Castle decor can add visual interest for fish. They also protect your fish to rest and passageways to keep them entertained.

Driftwood

Driftwood can be part of most aquascapes. But, natural driftwood is more suited for planted aquariums. It can anchor individual freshwater aquarium plants and provide hiding spots for fish.

Aquarium Cave Ideas

Caves make for excellent fish tank decor because they give hiding places to timid fish or fish that hide.

Not only do they protect fish, but aquarium caves can also act as a food source for fish, snails, and shrimp. Why? When algae grow on the outside of the cave decor, your pets will eat it up from time to time.

Statue Decor

Statues can be of other animals or people. They can also act as feeders for algae-eating snails and algae eater fish when algae grow on the surface. Choose a size that can fit your aquarium.

Live Plants

Live plants add beauty to any fish tank. Plants also help get rid of waste material and replenish oxygen for fish. There are different kinds of aquarium plants based on the position they occupy within the tank. But, you can mix and match and come up with a unique layout.
