Where most aquarium caves are bulky shells that dominate the tank, this one runs flat and narrow along the bottom — burying invisibly under sand or gravel to create a long underground tunnel system that shrimp, fry and corydoras claim as breeding territory. Choose left-facing or right-facing to match your tank's flow direction. UK 3D-printed in our Northumberland workshop from aquarium-safe PETG.\u003c\/p\u003e\n\n\u003ch2\u003eWhy a long buried tunnel works for breeders\u003c\/h2\u003e\n\u003cp\u003eShrimp and small fish breed best when they have enclosed, low-flow territory away from tankmates. A long buried tunnel gives them that — multiple internal feet of dark, sheltered space where berried shrimp can hide and fry can grow without being eaten. Unlike a single-chamber cave, the tunnel length means a whole colony can claim it at once. Established breeders use this kind of setup specifically to increase fry survival rates.\u003c\/p\u003e\n\n\u003ch2\u003eWhy left or right?\u003c\/h2\u003e\n\u003cp\u003eThe tunnel openings face one direction. Pick the variant that matches your tank — if your filter outflow runs left-to-right, choose right-facing so the tunnel entrance faces against the flow (calmer water inside the tunnel). For breeding tanks specifically, this small detail matters: shrimp avoid high-flow entrances. The mirror variants exist so you don't have to compromise on placement.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eLong thin tunnel shape — runs along the tank bottom, fully buries under substrate\u003c\/li\u003e\n  \u003cli\u003eLeft or right facing variants — match your tank flow direction\u003c\/li\u003e\n  \u003cli\u003eHidden once buried — only the tunnel opening shows\u003c\/li\u003e\n  \u003cli\u003eDesigned for shrimp breeding tanks, fry grow-outs and planted nano setups\u003c\/li\u003e\n  \u003cli\u003eSmooth interior — safe for delicate fins, shrimp moults and tiny fry\u003c\/li\u003e\n  \u003cli\u003e3D-printed in Northumberland, UK from aquarium-safe PETG\u003c\/li\u003e\n  \u003cli\u003eEncourages natural foraging and burrow-style hiding behaviour\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 174 × 73 × 62 mm (tunnel opening 75 mm wide)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge size:\u003c\/strong\u003e 222 × 89 × 80 mm (tunnel opening 93 mm wide)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariants:\u003c\/strong\u003e Standard-Left, Standard-Right, Large-Left, Large-Right\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e Buried under substrate along the tank bottom\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 Northumberland, 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 for these setups\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eNeocaridina and Caridina shrimp breeding tanks\u003c\/li\u003e\n  \u003cli\u003eCorydoras spawning and fry grow-out tanks\u003c\/li\u003e\n  \u003cli\u003ePlanted nano communities (chili rasbora, ember tetra, CPD)\u003c\/li\u003e\n  \u003cli\u003eEndler and guppy fry grow-out tanks\u003c\/li\u003e\n  \u003cli\u003eKuhli loach habitat enrichment\u003c\/li\u003e\n  \u003cli\u003eAquascapes where decor needs to be invisible\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to set it up for breeding\u003c\/h2\u003e\n\u003col\u003e\n  \u003cli\u003ePlace the tunnel along the back or side of the tank, opening facing away from filter flow\u003c\/li\u003e\n  \u003cli\u003eCover the top and sides with substrate (sand or fine gravel works best)\u003c\/li\u003e\n  \u003cli\u003eLeave the entrance opening clear\u003c\/li\u003e\n  \u003cli\u003ePlant moss carpets or low-light plants directly on top to disguise further\u003c\/li\u003e\n  \u003cli\u003eWithin days, shrimp and bottom-dwellers will claim it as a breeding territory\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow does this differ from your other underground cave?\u003c\/h3\u003e\n\u003cp\u003eShape and length. Our Underground Corner Cave is a square 135×135mm shell designed for the back 90° corner. This one is a long thin 174×73mm tunnel designed to run along the tank bottom. Choose this for shrimp breeding tanks where you want longer hidden territory; choose the corner cave for general nano-tank shelter in the back corner.\u003c\/p\u003e\n\n\u003ch3\u003eWhich direction (left or right) should I choose?\u003c\/h3\u003e\n\u003cp\u003eLook at your filter outflow direction. If water flows left-to-right across your tank, pick right-facing so the tunnel opens against the flow (calmer interior). If water flows right-to-left, pick left-facing. For breeding tanks specifically, lower interior flow improves fry survival.\u003c\/p\u003e\n\n\u003ch3\u003eWill the substrate weight crush it?\u003c\/h3\u003e\n\u003cp\u003eNo — PETG is rigid and the tunnel is engineered to take substrate load. You can cover it with several centimetres of sand or gravel without warping.\u003c\/p\u003e\n\n\u003ch3\u003eIs it safe for shrimp colonies?\u003c\/h3\u003e\n\u003cp\u003eYes. PETG is shrimp-safe (no copper, no leaching). The smooth interior won't catch moults. The long enclosed space is specifically suited to breeding colonies — berried females retreat inside to give birth.\u003c\/p\u003e\n\n\u003ch3\u003eWill fry actually grow inside?\u003c\/h3\u003e\n\u003cp\u003eYes — shrimplets, corydoras fry and small livebearer fry use the tunnel as a grow-out hiding zone away from larger tankmates. Many buyers report visible fry survival increases after adding one.\u003c\/p\u003e\n\n\u003ch3\u003eCan I plant on top?\u003c\/h3\u003e\n\u003cp\u003eYes — low-light plants like cryptocoryne, moss carpets or anubias work beautifully directly above the buried tunnel. Roots grow around the structure.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I clean it?\u003c\/h3\u003e\n\u003cp\u003eMost buyers leave it buried permanently — debris washes through naturally with water changes. If you want to deep-clean, lift gently from substrate, rinse in tank water, and reposition. Never use soap or detergent.\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 Northumberland workshop in aquarium-safe PETG.

The main reason suction cups fail is algae or biofilm on the glass surface; clean the mounting area before installing. If grip weakens after months in a tank, briefly remove and warm the cups in tap water to restore flexibility.\u003c\/p\u003e\n\n\u003ch3\u003eWill my betta actually use it?\u003c\/h3\u003e\n\u003cp\u003eMost do within 24-48 hours. Bettas are naturally curious and will explore the ledge as new tank furniture. If your fish doesn't use it immediately, try repositioning closer to the surface (within 3-5cm) — bettas favour shallower rest spots when they want to breathe air.\u003c\/p\u003e\n\n\u003ch3\u003eIs it safe for shrimp?\u003c\/h3\u003e\n\u003cp\u003eYes.

In larger tanks, spread them further apart to create distinct territories. For very small tanks (under 20L), you might prefer to use one or two and store the third as a swap-out.\u003c\/p\u003e\n\n\u003ch3\u003eIs it really safe for shrimp colonies?\u003c\/h3\u003e\n\u003cp\u003eYes. PETG is shrimp-safe (no copper, no leaching) and the smooth interiors won't catch moults. The multi-piece set is particularly good for shrimp because colonies naturally spread out — multiple hides means multiple breeding and grazing zones.\u003c\/p\u003e\n\n\u003ch3\u003eCan I bury the hides?\u003c\/h3\u003e\n\u003cp\u003eThey're designed to sit on top of substrate, but you can partially bury the bases for a more rooted look. Fully burying them defeats the point — the sculptural shape is meant to be visible.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I arrange three pieces in a tank?\u003c\/h3\u003e\n\u003cp\u003eAvoid placing all three in a line. Try a triangle arrangement with one as a focal point and two flanking, or scatter them with driftwood and plants between. Asymmetric placement always looks more natural than symmetric.\u003c\/p\u003e\n\n\u003ch3\u003eWill my fish use all three?\u003c\/h3\u003e\n\u003cp\u003eAlmost always — within a few days, individual fish or shrimp claim preferred hides.

The 2.5 cm openings are sized for typical community fish — corydoras, small plecos and shrimp all fit through comfortably.
