RED TAIL FISH 9.5 L Acrylic Aquarium Kit with Hidden Filter and LED Light

RED TAIL FISH is a 2.5-gallon (9.46 L) acrylic aquarium kit designed to house small fish and shrimp, with a concealed back filtration system that keeps equipment out of the main display.

• Hidden back filtration — keeps filter equipment out of view and leaves more room to shape the aquascape.
• Physical, biochemical, and pump filtration compartments — provide an environment for nitrifying bacteria and are designed to keep water clear for up to 1 month.
• Quiet operation under 18 dB — helps create a calmer aquarium setting at home or in an office.
• One-piece, full-covered tank with rounded corners — reduces the risk of accidental contact.
• High-impact-resistant acrylic — makes the tank lightweight to handle and reduces the risk of breakage.

This compact aquarium is made for a small aquatic display where visible equipment can take away from the view. Its concealed filtration layout gives you more freedom to arrange the aquascape, while the quiet pump operation suits shared indoor spaces such as a home or office. The kit is intended for beginners as well as fishkeepers setting up a small tank.

Which fish and aquatic pets is this aquarium designed for?

The 2.5-gallon tank is intended for small fish and shrimp, and its pump has three adjustable flow-strength settings. The listed suitable inhabitants include bettas, guppies, shrimp, angelfish, and snails. Adjusting the flow lets you select among three pump strengths for different small aquatic animals.

• Three-level adjustable water flow.
• Suitable for the listed small fish and aquatic animals, including bettas, guppies, shrimp, angelfish, and snails.

How does the hidden filtration system work?

Water passes through separate physical-filtration, biochemical-filtration, and water-pump compartments in the rear partition. This arrangement provides a cultivation environment for nitrifying bacteria; the system is designed to keep water clear for up to 1 month. The filtration is built into the tank layout rather than displayed as separate equipment in the main viewing area.

• Three distinct rear compartments for physical filtration, biochemical filtration, and the pump.
• Concealed equipment supports an open aquascape view.

What comes in the aquarium kit?

The kit includes the 2.5-gallon aquarium, a detachable lid, an LED light, a quiet water pump, filter sponge in a package intended for 6 months, eight bio filter balls, a dual-port USB charger, a PC transparent hose, and a user manual. These supplied components provide the tank, lighting, pump, filter media, and connection accessories for setting up the kit.

• Detachable lid and LED light.
• Filter sponge package and eight bio filter balls.
• Dual-port USB charger, PC transparent hose, and user manual.

How are the tank shape, water return, and noise designed?

The tank has a one-piece, full-covered form with rounded corners, and the lid is detachable. Its rear water-return path distributes flow evenly through the aquarium heater positioned at the back, helping avoid localized temperature differences for sensitive organisms such as Neocaridina shrimp. The pump operates below 18 dB, a quiet design intended to reduce fish stress and make the aquarium more comfortable in home or office surroundings.

• Rounded corners reduce the risk of accidental contact.
• Even rear water flow helps avoid localized temperature differences.
• Quiet pump operation is under 18 dB.

RED TAIL FISH is a fit for beginners and for people who want a compact aquarium with concealed filtration, adjustable flow, and included lighting and filter media. The lightweight, impact-resistant acrylic construction is also suited to homes with children or pets, where reducing the risk of breakage matters. It is a small-tank setup for the aquatic animals listed above, with a 2.5-gallon capacity and an integrated rear filtration design.
