Description
Cascading coral displays, weird and wonderful critters and game-changing new tank designs make the Invertebrilliant Collection a must-have for Megaquarium enthusiasts!

The Invertebrilliant Collection includes a hand-picked selection of the most weird and wonderful, plus the tools required to show them at their very best!
Critters to collect
The collection features 15 new animals from across the invertebrate spectrum: the punchy Boxing Shrimp, striking Hammer Coral and fluorescent Variable Neon Slug to name but a few.
Backdrops and Centerpieces
Designed specifically to go at the back of your tanks, Backdrops offer new opportunities to create dazzling vertical coral displays.
A world beneath your feet
Underfloor Tanks offer a bird's eye view of the reef, which is sure to delight and amaze your guests. Meanwhile, crafty curators will exploit the underfloor nature of these tanks to squeeze even more from their aquarium layouts!
Up close and personal
Magnifying Tanks zoom in on diminuitive species, allowing guests to view them in high detail. Savvy aquarists will use them to maximise the prestige generated from these miniature marvels.
Vegetation station
A selection of new plants can be mounted among your corals on Backdrops and Centerpieces. This brings new strategic and aesthetic depths to the design challenge.
The list goes on!
The fun continues with efficiency boosting accessories, an invertebrate-themed poster and new food and drink additions.
