Before You Buy: This ornament requires an air pump and standard 3/16" (4/6 mm) airline tubing (not included).

Lively Bubble Animation: Connect the airline to send a stream of bubbles from the hippo’s mouth—airflow makes the jaw appear to open and close for a fun, eye-catching effect.

Adds Oxygen & Movement: Fine bubbles boost surface agitation and help improve dissolved oxygen, supporting a healthier environment for community fish.

Aquarium-Friendly Resin: Cast from inert, colorfast resin with smooth edges; suitable for freshwater and marine tanks. Rinse before first use.

Simple Setup, Stable Placement: Sits flat on sand or gravel; hidden inlet keeps tubing tidy. Use an inline air valve (optional) to dial in bubble size and mouth motion.

Fits Many Aquascapes: Works as a playful focal point in planted, rocky, or themed layouts—also a great gift for fish keepers and kids.
