Review: Fluval hang on breeding box - Honestly the best ever breeding box i have ever purchased space savings hangs on the outside once connected to air supply fills itself. No instructions needed self explanatory up and running in 5 minutes Recommend purchase will be buying another Review: Clean, quiet, and stress-free—ideal for fry, isolation, or breeding without crowding your main tank. - Mounted this on a 120L community tank to isolate fry and a stressed guppy—worked spot-on. It hangs externally, so it doesn’t take up space inside the tank. Water circulates from the main tank using an air pump (not included), keeping temperature and chemistry consistent. No heater needed, no separate filtration—just plug in and go. Setup took about 10 minutes. Suction cups and brackets hold firm, even when full. Flow’s gentle—no risk of fry getting tossed around. I’ve used it for guppy fry, shrimp, and even a short quarantine stint. Easy to observe, feed, and clean. 📦 Features & Specs Capacity: 1.1 litres Mounting: Hang-on design with secure brackets Flow System: Air-lift driven—uses tank water for circulation Compartments: Optional dividers for multiple fry or isolation zones Material: Clear acrylic—easy viewing, solid build Extras: Includes tubing and flow adjuster (air pump not included) 🧪 Performance Water Quality: Stays stable—no separate heater or filter needed Noise Level: Near silent—just a soft bubbling from the air pump Cleaning: Easy to rinse and wipe down—no awkward corners Visibility: Clear sides make it easy to monitor fry or isolated fish 👍 Pros ✅ External mount—saves tank space ✅ Gentle flow—safe for fry and shrimp ✅ Stable conditions—uses tank water ✅ Easy setup—no tools needed ✅ Optional dividers—customise layout 👎 Cons ❌ Air pump not included—must buy separately ❌ Limited size—best for small fish or fry ❌ Needs level tank edge—check fit before mounting ❌ No lid—watch for jumpers or evaporation 🧭 Personal Verdict If you’re breeding, isolating, or just want a clean way to manage fry without stressing your main tank, this box is a tidy bit of kit. I’ve used it for guppies and shrimp—no drama, no losses. It’s earned its spot in the gear stash. ## Features - Multi-purpose - Safe & secure tank for breeding, isolating or acclimatizing fish - Space-saving design, easily installs on the exterior of the aquarium - Fish fry slip through the v-shaped separator and are safely segregated from adults - Measures 16 cm (6 1/3") wide and holds 1.2 liters (0.3 us gal.) of water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005QRDDJ2 | | Best Sellers Rank | 6,716 in Pet Supplies ( See Top 100 in Pet Supplies ) 3 in Breeding Tanks for Fish 311 in Aquarium Accessories | | Brand | Fluval | | Brand Name | Fluval | | Colour | klar | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 6,081 Reviews | | Global Trade Identification Number | 00015561109420 | | Included Components | Breeding box with cover, Intake tube, V-shape separator, Leveling adjuster, Air valve, Airline tube 12" (30 cm), Discharge cap, Intake extension, O-Ring, Strainer, 2 x Slit plates for discharging water (1 thick frame - 3 bars, 1 thin frame - 5 bars) | | Item Dimensions L x W x H | 17.3L x 13.2W x 13.5H centimetres | | Item Shape | Rectangular | | Item Type Name | Breeding Box | | Item Weight | 0.7 Pounds | | Item weight | 0.7 Pounds | | Manufacturer | Rolf C Hagen UK Ltd | | Manufacturer Part Number | 10942 | | Material | Glass | | Material Type | Glass | | Model Number | 10942 | | Pet Type | Fish | | Product Style | Modern & Minimalist | | Product dimensions | 17.3L x 13.2W x 13.5H centimetres | | Set Name | Fluval Multi-Chamber Breeding Box Set | | Special Features | Hang-on Design | | Special feature | Hang-on Design | | Specific Uses For Product | Aquarium | | Tank Volume | 1.9 Litres | | Tank volume | 1.9 Litres | | Target Species | Fish | | UPC | 015561109420 | | Unit Count | 1 count | | Vivarium Type | Fish Breeding Tank | ## Product Details - **Brand:** Fluval - **Colour:** klar - **Item weight:** 0.7 Pounds - **Material:** Glass - **Product dimensions:** 17.3L x 13.2W x 13.5H centimetres - **Shape:** Rectangular - **Special feature:** Hang-on Design - **Specific uses for product:** Aquarium - **Style:** Modern & Minimalist - **Tank volume:** 1.9 Litres ## Images ![Fluval Hang-On Breeding Box, Medium, 1.1 Litre - Image 1](https://m.media-amazon.com/images/I/71taM+M+UYL.jpg) ![Fluval Hang-On Breeding Box, Medium, 1.1 Litre - Image 2](https://m.media-amazon.com/images/I/513qgDr4txL.jpg) ![Fluval Hang-On Breeding Box, Medium, 1.1 Litre - Image 3](https://m.media-amazon.com/images/I/619Of61S35L.jpg) ![Fluval Hang-On Breeding Box, Medium, 1.1 Litre - Image 4](https://m.media-amazon.com/images/I/61ltl7ohVVL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: what size is the inlet tubing/piping if i was to plumb it up to a power head?** A: You need to connect the piping to an air pump, not a power head. It fits regular 4/6mm air tubing **Q: How far does the box stick out if hind from back of side of tank?** A: Depends on the thickness of the rim, mine sticks out 100mm or 4 inches **Q: I have a biorb round tank, would this fit on the outside?** A: No this is really for a tank that has got a lid. It didn’t fit my tank as mine has a lid. So unless the tank has no lid. Then it won’t fit. **Q: Can this be used as a hospital tank for a siamese fighting fish (beta)?** A: It uses the same water as your main tank so it would depend on why you are hospitalising your Beta. For injuries it would be ok but not for disease treatment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fluval hang on breeding box *by K***Y on 9 February 2026* Honestly the best ever breeding box i have ever purchased space savings hangs on the outside once connected to air supply fills itself.

Sturdy, well-designed, functional… I wish I’d bought this before wasting money on DIY efforts and nets. Babies are safe and secure, it’s easy to gaze lovingly at them, there are no fears about parameters… there is nothing not to love about this. ## Frequently Bought Together - Fluval Multi-Chamber Holding and Breeding Box, Medium - Penn-Plax AN2 Aqua Nursery and Hatchery Breeding Box for Your Aquarium - Help Protect Baby Fish from Predators - SAVITA 6 Pieces 13x10.24in 7 Count Plastic Needlepoint Canvas White Plastic mesh Sheets for Embroidery Crafting and Knit and Crochet Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/49943313-fluval-hang-on-breeding-box-medium-1-1-litre](https://www.desertcart.de/products/49943313-fluval-hang-on-breeding-box-medium-1-1-litre) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-07*
