Due to an industry wide raw material shortage, we are experiencing extended lead times.

Our estimated lead time is now 8-12 weeks.

We appreciate your patience.

Available in wide range of common sizes and some custom options, Crevice aquarium backgrounds from Universal Rocks are extremely detailed, and designed to take up only a fraction of your tank’s space, with a maximum 3" extension in featured and rocky areas.  This background was molded from real basalt rocks located in a remote outcrop south of Sydney Australia.


Cutting a background to fit your specific tank size will take a bit more time in light of the various features, but once installed we think you’ll agree that it’s worth it in both appearance and stunning realism.  Get in touch with our staff for answers to questions about shipping or installation, and be sure to browse our custom aquarium backgrounds section for more options and size/design configurations.

We invite you to discover why Universal Rocks is trusted by industry experts, celebrities and renowned landscape architects everywhere. Browse our full line of faux rocks products, or explore our vast collection of custom aquarium backgrounds and other popular artificial rock decorations.
