Aquarium Suction Cups Fixi 13×30 mm, black — pack of 50

Fixi black aquarium suction cups, 13×30 mm, pack of 50, are small adhesive fixtures designed to secure tubing, heaters, air lines and decorations to smooth glass surfaces in freshwater and marine aquariums. Each cup is molded to provide reliable suction on non-porous surfaces and allows repeated repositioning without leaving residue. The compact 13×30 mm size fits most common aquarium tubing and accessory anchors while the black color blends with dark backgrounds and hides minor marks, supporting a tidy installation of equipment along the tank wall.

Advantages

These Fixi suction cups are made for repeated use on smooth glass and similar non-porous surfaces and deliver stable holding force for lightweight aquarium accessories. The uniform shape and size across the pack make installation consistent and time-efficient. The black finish reduces visual distraction and helps conceal tubing attachments. Their small footprint minimizes interference with aquarium inhabitants and décor while keeping equipment organized and preventing drifting.

How to use

Ensure the glass or acrylic surface is clean, dry and free of algae, oils or residues before applying the suction cup. Press the cup firmly against the surface to expel air and create a vacuum; attach tubing or accessory post into the cup's opening and check that the item is held securely. For repositioning, gently pull the tab or edge to release the seal, clean both surfaces if necessary and reapply in the new location. Regularly inspect suction cups and the secured items to confirm continued adhesion and correct positioning.

Usage recommendations

For best performance, avoid attaching suction cups to textured, scratched or porous surfaces. Periodic cleaning of both the suction cup and mounting surface with freshwater helps maintain suction strength. In tanks with strong water flow or heavy equipment, use multiple suction cups to distribute load and reduce the risk of detachment.
