About This

• Blocks the Dangerous Long Slot – Precision-engineered to fully cover the vulnerable rear opening. Effectively prevents jump-prone fish (like bettas, gobies, or shrimp) from escaping and stops curious cat paws from reaching into your tank.
• Dual-Function Design – Works as both a protective barrier and a practical tool for aquatic plant propagation. The smooth cover plate provides an ideal surface to suspend plant clippings in the water, allowing them to float and root safely without being sucked into the filter compartment.
• Perfect-Fit Compatibility – Custom-designed specifically for the 5-gallon aquarium kit. Matches the exact length and width of the original lid’s slot opening for seamless integration with your existing setup – no gaps, no wobbling.
• Easy Drop-In Installation – Simply place the cover plate into the slot on your lid. No tools, adhesives, or permanent modifications required. Removes instantly in seconds for feeding, maintenance, or netting fish.
• Durable – Constructed from high-quality, materials that are safe for freshwater and saltwater aquariums. Resistant to warping, cracking, and discoloration under aquarium lighting.
