Description
Product Overview
The Marina Cubus Betta Kit is a thoughtfully engineered aquarium solution designed specifically for the vibrant Betta splendens, commonly known as Siamese fighting fish. Constructed from high-quality tempered glass, the 0.9‑gallon (3.4 L) tank offers crystal‑clear visibility, allowing owners to fully appreciate the dazzling colors and graceful movements of their betta. The compact cubic shape, measuring 5.9 × 5.9 × 5.9 inches (15 × 15 × 15 cm), fits comfortably on a desk, nightstand, or office shelf without overwhelming the surrounding space. A flexible, energy‑efficient clip‑on lighting system incorporates three powerful LED bulbs that emit a balanced spectrum, enhancing the natural iridescence of the fish while consuming minimal electricity. The lid features a dedicated breathing opening that promotes optimal oxygen exchange, and the pedestal base is coated with a non‑slip material to protect furniture from water damage. All components—including the tank, lid, lighting module, and pedestal—arrive pre‑assembled, requiring only the addition of water, substrate, and the fish, making the setup process straightforward for beginners and seasoned hobbyists alike.

Usage
This aquarium is ideally suited for a variety of indoor environments. In a home setting, it serves as an eye‑catching decorative piece in living rooms, bedrooms, or study areas, providing a calming aquatic focal point that can reduce stress and improve air quality. For office spaces, the compact design fits neatly on a cubicle desk or conference room table, offering employees a soothing visual break during busy workdays. The kit’s low maintenance requirements—thanks to the built‑in filtration and easy‑access lid—make it perfect for users who desire a vibrant pet without the commitment of a large, complex system. The LED lighting can be adjusted to simulate natural day‑night cycles, supporting the betta’s health and encouraging natural behaviors such as flaring and fin displays. Additionally, the aquarium’s sturdy construction ensures safe transport, allowing owners to relocate the tank between rooms or even take it on short trips, provided the water is securely sealed.

FAQ
What size fish can I keep in the 0.9‑gallon tank?
The tank is specifically sized for a single Betta splendens. Adding other fish may lead to overcrowding and stress, so we recommend keeping only one betta per unit.
Do I need additional filtration for this aquarium?
The kit includes a built‑in gentle filtration system that circulates water without creating strong currents, which is ideal for bettas. For those who prefer extra water clarity, a small sponge filter can be added, but it is not required.
How often should I change the water?
We suggest performing a partial water change of 25‑30 % every week to maintain optimal water quality. Full water changes can be done every 2‑3 weeks, depending on tank conditions and fish health.
Can I use the LED light on a timer?
Yes, the LED module is compatible with standard aquarium timers, allowing you to set a consistent day‑night cycle that supports the betta’s natural rhythm.
Is the kit covered by a warranty?
All Marina Cubus products come with a one‑year limited warranty covering manufacturing defects. Contact our support team for warranty claims or replacement parts.
