Suction cup for aquarium Fixi 5×30 mm transparent pack of 50

Transparent suction cups by Fixi, size 5×30 mm, supplied in a pack of 50. These small clear mounts are designed for secure attachment of tubing, heater cables, air lines, decorations and other lightweight components to glass or acrylic aquarium walls. The neutral transparent finish minimises visual impact, making them suitable for freshwater and marine tanks where a discreet mounting point is required. Each cup features a concave shape that creates suction against smooth surfaces and an integrated notch to hold cords and tubing in place for tidy routing and reliable positioning.

Advantages

The suction cups are sold in a multi-pack of 50, providing spares and multiple mounting points for larger installations. Their transparent material reduces visibility inside the tank while maintaining grip on smooth glass or acrylic. The compact 5×30 mm size is suitable for small-diameter tubing and thin cables and allows flexible placement and easy repositioning without tools. Construction is intended for general-purpose aquarium use in both freshwater and marine environments.

Suitable for

• Securing airline tubing, heater leads and sensor cables
• Attaching small decorations, LED wires or oxygen tubing to aquarium walls
• Organising cords and routing tubing along glass or acrylic panels
• Temporary mounting where non-permanent, repositionable attachment is required

How to use

Before installation, clean the glass or acrylic surface to remove dust, algae or silicone residue for best adhesion. Press the concave side of the suction cup firmly against the smooth surface, ensuring there is no trapped air between the cup and the aquarium wall. Insert tubing or cable into the integrated notch and adjust position as needed. To reposition or remove, gently lift the edge of the cup to break the seal and move to the new location. Regularly inspect mounted items and reapply cups if grip weakens over time.

Usage recommendations

For reliable performance, avoid applying suction cups to textured, frosted or heavily curved surfaces. Replace any cup that shows signs of hardening, cracking or reduced flexibility. When using in marine aquaria, periodically check for salt buildup and clean cups with fresh water to maintain adhesion.
