Designed for family recreation and swim training, Swii combines the stability of a highly buoyant kickboard with smooth dual-propeller assistance. Two speed modes at 0.6 / 1.0 m/s (1.34 / 2.24 mph), intuitive two-hand control, and support for users up to 100 kg (220.5 lb) make it easy to enjoy in pools and calm water.
Buoyancy & Control — A stable kickboard-style design supports developing swimmers, while two speed modes adapt from gentle practice to faster recreational use.
Smart Safety — Multi-color status lights show battery and operating status, while SublueGo supports speed control, child safety lock, indicator-light settings, and self-cleaning.
Battery & Runtime — Every standard Swii includes 1 removable 98 Wh battery, providing up to 30 minutes of normal use. The 98 Wh battery is no longer offered as an additional battery option.
Extra Battery Option — The current “+ Extra Battery” option adds 1 removable 158 Wh battery, providing up to 45 minutes of normal use when installed. This is in addition to the included 98 Wh battery, for 2 batteries total.
Feeding & Diet
An opportunistic omnivore, the Seahorse will scavenge detritus, uneaten food, and algae — making it a natural cleanup crew member. Supplement with small meaty foods like mysis shrimp or pellets 2–3x per week if natural food sources are limited.
Care & Water Parameters
The Seahorse thrives in stable, well-maintained reef conditions. Target parameters: temperature 72–78°F, salinity 1.025–1.026 SG, pH 8.1–8.4, and alkalinity 8–12 dKH. A mature, established tank of at least 20 gallons is recommended.
Reef & Tank Compatibility
Generally considered reef-safe. The Seahorse coexists well with most corals and peaceful fish. Use caution with very small invertebrates or slow-moving tankmates. Provide ample rockwork and hiding spots to reduce territorial behavior.
Size & Growth
Seahorses are typically shipped at 0.5–1.5 inches. They are slow-growing and generally remain small, making them well-suited for nano and mid-size reef systems.
