The refined curved silhouette tucks flush against the back-corner glass, while the open arch creates a natural in-and-out passage for shrimp, bettas and nano fish. A subtler alternative to bolder cave designs — minimalist, structural, and unmistakably built for design-led aquascapes. UK 3D-printed in aquarium-safe PETG.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the arch shape works\u003c\/h2\u003e\n\u003cp\u003eMost aquarium caves are closed shells with a single opening — visually heavy, often clashing with planted-tank aesthetics. The arch design solves that. The open span lets light pass through, gives fish multiple entry and exit points, and reads as a natural rock arch rather than a moulded ornament. It's the cave for aquascapers whose tanks are entered into competitions — or just photographed often.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSculpted arch silhouette — refined, minimalist alternative to closed caves\u003c\/li\u003e\n  \u003cli\u003eCorner-fit shape — sits flush against the back 90° corner glass\u003c\/li\u003e\n  \u003cli\u003eFlat top for substrate or moss layering — disappears further into the scape\u003c\/li\u003e\n  \u003cli\u003eOpen span — multiple entry points, light passes through, fish never feel trapped\u003c\/li\u003e\n  \u003cli\u003eSmooth interior — safe for delicate fins and shrimp moults\u003c\/li\u003e\n  \u003cli\u003e3D-printed in the UK from aquarium-safe PETG plastic\u003c\/li\u003e\n  \u003cli\u003eDesigned for planted, blackwater, hardscape and minimalist aquascapes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aquarium-safe PETG plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard size:\u003c\/strong\u003e 135 × 135 × 70 mm (tunnel openings 35 × 30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge size:\u003c\/strong\u003e 191 × 191 × 100 mm (tunnel openings 49 × 42 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Sculpted arch \/ bridge profile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e 90-degree back corner of tank (visible, above substrate)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColours:\u003c\/strong\u003e Black, White, Marble Effect, Moss Green, Sand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e United Kingdom\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blubber Cove\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSuitable species\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eNeocaridina and Caridina shrimp\u003c\/li\u003e\n  \u003cli\u003eBetta splendens (Siamese fighting fish)\u003c\/li\u003e\n  \u003cli\u003eCorydoras (panda, bronze, pygmaeus)\u003c\/li\u003e\n  \u003cli\u003eKuhli loaches and weather loaches\u003c\/li\u003e\n  \u003cli\u003eNano community fish — chili rasbora, ember tetra, celestial pearl danio\u003c\/li\u003e\n  \u003cli\u003eDwarf cichlids (apistogramma, kribensis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eChoosing the right size\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard (135 × 135 × 70 mm):\u003c\/strong\u003e nano tanks 20–60 litres, shrimp colonies, single bettas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge (191 × 191 × 100 mm):\u003c\/strong\u003e mid-size tanks 60–200 litres, communities, larger nano-fish shoals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eAquascape styling tips\u003c\/h2\u003e\n\u003cp\u003eThe arch shape pairs especially well with: java fern and anubias mounted on driftwood adjacent to the cave · moss carpets across the flat top · iwagumi-style stone arrangements either side · low-light substrate (aquasoil, sand). Avoid overplanting directly in front of the arch opening — the negative space inside the arch is part of the visual.\u003c\/p\u003e\n\n\u003ch2\u003eAlso suitable for reptile and amphibian setups\u003c\/h2\u003e\n\u003cp\u003eThe arch design also works as a vivarium or terrarium hide. Compatible with axolotl tanks, crested gecko enclosures, leopard gecko setups and small reptile\/amphibian habitats. PETG is non-toxic in humid environments and the open arch makes it easy for pets to enter and exit.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow is this different from your other corner caves?\u003c\/h3\u003e\n\u003cp\u003eThe shape. This is the sculpted arch — a refined, open silhouette that suits minimalist and planted aquascapes. Our other corner caves are: the Tall Mangrove (bolder pillared design for vertical interest), the Wide Corner (extra-wide entrance for big-bodied fish), and the Underground (designed to be buried under substrate).\u003c\/p\u003e\n\n\u003ch3\u003eWill my fish actually use it?\u003c\/h3\u003e\n\u003cp\u003eYes. The open arch means fish never feel trapped, which makes them more likely to use it as a daytime rest spot. Shrimp claim the interior shadow as a colony grazing zone, and bettas often perch under the arch top.\u003c\/p\u003e\n\n\u003ch3\u003eIs it safe for shrimp?\u003c\/h3\u003e\n\u003cp\u003eYes. PETG is shrimp-safe with no copper or leaching. The smooth interior won't catch moults.\u003c\/p\u003e\n\n\u003ch3\u003eCan I plant on top of it?\u003c\/h3\u003e\n\u003cp\u003eYes — the flat top is designed for moss carpets, low-light plants or hardscape additions. Many buyers layer Java moss or anubias directly across the top for a fully natural look.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my tank?\u003c\/h3\u003e\n\u003cp\u003eThe Standard fits tanks from 20 litres up (Fluval Spec, nano cubes). The Large suits 60–200 litre tanks. Both need a 90-degree internal corner — most rectangular tanks.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it work in a bow-front or curved tank?\u003c\/h3\u003e\n\u003cp\u003eNot ideally — the corner-fit shape is designed for 90° back corners. For curved tanks, our Aquarium Cave Hideaway (rounded dome) sits better.\u003c\/p\u003e\n\n\u003ch2\u003eWhy buy from Blubber Cove\u003c\/h2\u003e\n\u003cp\u003eOriginal aquascaper-designed pieces, 3D-printed to order in our UK workshop in aquarium-safe PETG.
