RS380B AQUARIUM ONLY (SIZE 38X25X47 CM) BLACK,PINK,BLUE

The RS 380B is a moulded aquarium tank measuring 38 × 25 × 47cm, sold under the RS brand and available with a choice of coloured trim/base (black, pink, or blue in this listing). Unlike some other RS tank kits on this site, the title specifies this one is sold as "aquarium only" -- i.e. the bare tank itself, without a bundled top, light, or filter.

Moulded tanks like this typically use a plastic base and frame with a glass or acrylic viewing panel, which tends to make them lighter and often more affordable than an all-glass tank of a similar size, while still giving a clean, finished look thanks to the coloured moulded trim -- a common construction style for compact, budget-friendly tanks aimed at bettas and small setups rather than large show aquariums.

Its taller-than-wide proportions (47cm height against a 38 × 25cm footprint) make it well suited to fish and plants that use vertical space, and give a nice display profile for a single centrepiece fish like a betta on a shelf or desk.

The colour trim options are purely cosmetic, letting the tank match different room decors or personal taste without affecting how it functions.

The three colour options let this fit different settings -- black for a more understated, gallery-style look that lets the fish and plants stand out, or pink/blue for a more playful, decorative presentation -- without any difference in the tank's actual construction or capacity between colour variants.

At 38 × 25 × 47cm, this tank has a gross volume of roughly 44.6 litres (38 × 25 × 47 ÷ 1000), though real usable volume will be somewhat less once substrate and water-level headroom are accounted for -- still a comfortably sized tank for a single betta, a small peaceful community, or a modest planted setup.

Since this listing is the tank only, plan on adding a lid, a small-to-medium filter (rated for roughly 40-50 litres), and a heater if you're keeping tropical fish in a room that runs below about 24°C. A low-wattage heater in the 50W range is typically appropriate for a tank this size in most home conditions.

Filled, this tank will weigh in the region of 45-50kg with water, substrate, and decor, so it needs a stable, level, weight-rated surface -- the moulded plastic base helps distribute weight evenly, but the surface underneath still needs to be solid and level.

Keep it out of direct sunlight to avoid algae blooms and temperature swings, and cycle the tank (run the filter for one to two weeks, ideally with a bacterial starter) before adding fish.

If the viewing panel is acrylic rather than glass (common in moulded-frame tanks like this), be aware acrylic scratches more easily than glass and needs softer cleaning tools -- check the product specifics if this matters to you, since care routines differ slightly between the two materials.

Caring for a moulded tank like the RS 380B day-to-day:

• Placement: level, stable, weight-rated surface, out of direct sunlight
• Cycling: 1-2 weeks running the filter before stocking, adding fish gradually
• Water changes: roughly 20-25% weekly for a lightly-to-moderately stocked tank this size
• Panel cleaning: use only aquarium-safe scrapers/pads on the viewing panel -- if it's acrylic rather than glass, avoid anything abrasive that could scratch it
• Moulded frame care: wipe down the coloured plastic trim periodically to prevent mineral/salt buildup, especially around any seams where the panel meets the frame
• Trim care: the coloured moulded base/frame is typically a painted or pigmented plastic -- avoid abrasive cleaners on it, a damp soft cloth is usually enough
• Stocking pace: introduce fish gradually over two to three weeks rather than stocking a ~45 litre tank fully on day one
• Water testing: keep basic ammonia/nitrite/pH tests on hand, particularly useful in the first few weeks after setup
• Evaporation: top up with dechlorinated water between water changes as levels drop, rather than only topping up on water-change day
• Seams and seals: on a moulded-frame tank the join between the plastic frame and the glass/acrylic panel is worth a quick visual check every so often, especially after the first few weeks of settling in, though a well-made unit like this shouldn't need any attention there under normal use

With basic upkeep, a moulded tank like this offers a light, affordable, good-looking home for a betta or small peaceful setup.
