Our range also includes accessories and replacement components to help you create a secure, discreet cover while maintaining excellent ventilation and light penetration.
Aquarium Jump Guards – Protect Your Marine Fish
An aquarium jump guard is one of the simplest ways to protect your fish from accidental escapes. Many marine species are natural jumpers, particularly when startled, chased by tankmates or disturbed during the night.
At Rock 'N' Critters, we offer a carefully selected range of aquarium mesh covers, DIY jump guard kits and ready-made lids to help keep your fish safely inside their aquarium without compromising its appearance.
Why Use an Aquarium Jump Guard?
Wrasses, gobies, dartfish, blennies and many other popular marine fish may jump from open-top aquariums.
A properly fitted jump guard provides a protective barrier across the aquarium opening, helping reduce the risk of fish escaping.
Unlike traditional solid glass or plastic lids, mesh aquarium covers also allow excellent ventilation and light transmission, making them particularly suitable for modern reef aquariums.
DIY Mesh Covers or Pre-Assembled Aquarium Lids?
Choosing the right aquarium cover depends on your tank's dimensions, design and equipment.
DIY Aquarium Mesh Covers
Our D-D JumpGuard Pro and Red Sea Aquarium Net Cover kits can be cut and assembled to fit a wide range of aquariums.
These systems are particularly useful for non-standard aquarium dimensions or installations requiring cut-outs around lighting brackets, overflow boxes and other equipment.
Pre-Assembled Aquarium Jump Guards
TMC Reef Guard covers offer a convenient alternative for compatible TMC aquariums.
Designed for specific Reef Habitat and Next Wave models, these covers provide a neat, purpose-made fit without the cutting and assembly required by universal DIY kits.
Choosing the Right Aquarium Cover
When selecting an aquarium jump guard, consider:
-
Aquarium dimensions: Measure the actual opening rather than relying solely on the aquarium's advertised size.
-
Equipment clearance: Allow for lighting brackets, pipework, overflow boxes and automatic feeders.
-
Cover compatibility: Check that pre-assembled covers match your exact aquarium model.
-
Mesh design: Choose a discreet mesh cover that maintains suitable light penetration and ventilation.
-
Access: Consider how easily the cover can be removed for feeding and maintenance.
For the best protection, ensure the cover fits securely and leaves no gaps through which fish could escape.
Jump Guard Accessories & Replacement Parts
We also stock accessories for selected aquarium cover systems, including cut-out components, brace bars, replacement mesh and feeding portals.
These allow you to customise an existing cover, accommodate new equipment or replace damaged components without purchasing an entirely new kit.
