This beautiful ledge-style fish tank background was created using a variety of natural rock ledges in Australia, and combining them together to produce those offered today.  All told, we offer 23 different sizes.  They’re a perfect addition to any aquarium, terrarium or reptile enclosure.  Fish absolutely love ledges for hiding and picking algae, and reptiles are just as fond of them when it comes to basking, hiding or resting.

The measurements listed are external tank measurements.

The backgrounds are around 1/2" to 3/4" shorter for each dimension listed to be close to fitting into a tank with the listed external measurements.

- Our ledge varies in size and protrudes in the smaller tank about 2” to 4” and the larger 3" to 7".


Our ledge aquarium backgrounds come in a variety of sizes, and protrusion depths, which vary from 2” to 4” in smaller tanks and anywhere from 3” to 7” for larger aquariums.  There’s plenty of room for heaters and other accessories, and each one is constructed from durable materials that retain their color and exquisite detail over extended periods of time.
