Aquarium Suction Cups Fixi 5×30 mm, black, pack of 50

Fixi aquarium suction cups, black, size 5×30 mm, pack of 50 are compact mounting supports designed to attach tubing, heater cables, air lines and lightweight accessories to glass or other smooth surfaces inside aquariums. These suction cups provide a non-permanent, tool-free fixing solution that allows for easy repositioning and removal. The black finish reduces visual distraction in planted or decorated tanks while the small footprint fits tight spaces and discrete installations.

Advantages

The suction cups are made from flexible, aquarium-safe material that forms a reliable seal on clean smooth surfaces. Supplied in a pack of 50, they are convenient for larger setups or multiple attachment points. Their compact 5×30 mm size balances holding capacity with low visibility. Installation requires no adhesives or drilling, preserving glass and silicone joins while enabling quick adjustments as layout or equipment changes.

Suitable for

• Securing flexible tubing for filters, pumps or CO2 systems
• Fixing air lines and small airline accessories
• Routing heater cables or power leads along tank walls
• Attaching lightweight decorations or sensors to glass

Key specifications

• Color: black
• Size: 5×30 mm (diameter × stem/shaft length)
• Material: flexible, aquarium-safe elastomer
• Pack quantity: 50 pieces
• Suitable surfaces: glass and other smooth, non-porous surfaces

How to use

Ensure the glass or smooth mounting surface is clean and free of algae, dust or silicone residue. Moisten the suction cup slightly with clean water to improve initial adhesion, press the cup firmly against the surface until it seats, then route the tubing or cable through the stem or secure it alongside the cup. To reposition, gently pull the lip of the suction cup to break the seal and move to the new location. For best results, avoid mounting on textured or curved surfaces that prevent a full seal.

Usage recommendations

Regularly inspect suction cups for signs of wear, hardening or loss of elasticity; replace compromised cups to prevent dropped items. In saltwater aquaria, rinse cups periodically to remove salt buildup and maintain adhesion. For heavier items consider using multiple suction cups or alternative mounting methods designed for greater load.
