Ships as two smaller pieces that slot together at the tank corner under your substrate. Once assembled and buried, it functions as a single corner cave; the join disappears under the substrate. UK 3D-printed in aquarium-safe PETG.\u003c\/p\u003e\n\n\u003ch2\u003eWhy a 2-piece design?\u003c\/h2\u003e\n\u003cp\u003eMany tanks aren't easy to drop decor into. Hooded tanks with tight access flaps, lidded nano cubes with small openings, planted tanks with cross-bracing, or built-in \/ wall-mounted aquariums all share the same problem: a single 200mm cave physically won't fit through the access. This cave solves that. Each piece is roughly 100mm — small enough to drop through almost any tank opening. You assemble the two halves at the corner under your substrate, bury, and the result is a single buried corner tunnel that buyers with standard open-top tanks would have bought as a one-piece.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e2-piece slot-together design — each piece fits through tight tank access openings\u003c\/li\u003e\n  \u003cli\u003eCorner-fit shape — sits against the back 90° corner of the tank\u003c\/li\u003e\n  \u003cli\u003eSlim 40mm profile — buries fully in shallow aquascape substrate\u003c\/li\u003e\n  \u003cli\u003eDesigned for hooded, lidded and access-limited tanks\u003c\/li\u003e\n  \u003cli\u003eSmooth interior — safe for delicate shrimp moults and fry\u003c\/li\u003e\n  \u003cli\u003e3D-printed in Northumberland, UK from aquarium-safe PETG\u003c\/li\u003e\n  \u003cli\u003eIdeal for shrimp colonies, corydoras and small community fish\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 (2 pieces):\u003c\/strong\u003e Piece 1: 105 × 40 × 40 mm · Piece 2: 100 × 42 × 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard assembled length:\u003c\/strong\u003e approximately 205mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge size (2 pieces):\u003c\/strong\u003e Piece 1: 140 × 52 × 48 mm · Piece 2: 132 × 52 × 48 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge assembled length:\u003c\/strong\u003e approximately 272mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e Back corner of tank, buried under substrate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubstrate depth needed:\u003c\/strong\u003e 4-5cm to fully bury Standard, 5-6cm for Large\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColours:\u003c\/strong\u003e Black, White, Beige, Marble Effect, Green\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\u003eIdeal for these tank types\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eHooded aquariums with limited top access (Fluval Flex, Marina, Aqueon kit tanks)\u003c\/li\u003e\n  \u003cli\u003eLidded nano cubes and bowfront tanks\u003c\/li\u003e\n  \u003cli\u003eCross-braced planted tanks where a single bulky piece won't drop through\u003c\/li\u003e\n  \u003cli\u003eBuilt-in or wall-mounted aquariums with restricted access\u003c\/li\u003e\n  \u003cli\u003eTanks where you're rescaping without fully draining — assemble piece-by-piece\u003c\/li\u003e\n  \u003cli\u003eStandard open-top tanks too — assembly is still quick and the result is identical\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\u003eCorydoras (panda, bronze, pygmaeus)\u003c\/li\u003e\n  \u003cli\u003eKuhli loaches and weather loaches\u003c\/li\u003e\n  \u003cli\u003eSmall community fish — chili rasbora, ember tetra, CPD\u003c\/li\u003e\n  \u003cli\u003eShrimp fry and small fry of any peaceful species\u003c\/li\u003e\n  \u003cli\u003eBristlenose plecos (Large size)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to install\u003c\/h2\u003e\n\u003col\u003e\n  \u003cli\u003eDrop each piece individually through your tank's access opening\u003c\/li\u003e\n  \u003cli\u003ePosition both pieces at the back corner of the tank, slot edges aligned\u003c\/li\u003e\n  \u003cli\u003ePush the pieces gently together — the slot join holds firm under substrate weight\u003c\/li\u003e\n  \u003cli\u003ePour sand, gravel or aquasoil over the top to bury\u003c\/li\u003e\n  \u003cli\u003eKeep tunnel openings clear at each end so fish can enter and exit\u003c\/li\u003e\n  \u003cli\u003eWithin hours, shrimp and bottom-dwellers explore and claim the cave\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch2\u003eHow is this different from your other corner caves?\u003c\/h2\u003e\n\u003cp\u003eThe shipping format. This one ships in two pieces specifically to drop through tight tank openings — useful if you have a hooded tank, lidded nano, or any setup where a single 200mm cave is too bulky to manoeuvre into position. Functionally, once assembled and buried, it works the same as a single-piece corner cave. Pick this if your tank access is restricted; pick our single-piece corner caves (Underground Corner, Slim Against-Glass) if you have open-top access.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3\u003eWill the two pieces stay together once buried?\u003c\/h3\u003e\n\u003cp\u003eYes — the slot join is designed to be load-bearing under substrate weight. Once buried, the substrate itself locks the pieces in place. The join becomes invisible under the substrate line.\u003c\/p\u003e\n\n\u003ch3\u003eCan I take it apart for cleaning?\u003c\/h3\u003e\n\u003cp\u003eYes — gently lift each piece during deep cleans, rinse in tank water, reposition and re-slot. Most owners leave it permanently buried; debris washes through naturally during water changes.\u003c\/p\u003e\n\n\u003ch3\u003eWill it look like two separate pieces in my tank?\u003c\/h3\u003e\n\u003cp\u003eNo — once buried under substrate, only the two tunnel openings (one at each end of the assembled cave) are visible. The join down the middle disappears completely under the substrate line.\u003c\/p\u003e\n\n\u003ch3\u003eWhat if I have an open-top tank?\u003c\/h3\u003e\n\u003cp\u003eIt still works fine — assembly takes about 30 seconds. But if you have full open-top access, our single-piece corner caves are slightly more convenient since there's nothing to assemble. This cave is specifically for buyers whose tank access is restricted.\u003c\/p\u003e\n\n\u003ch3\u003eIs it safe for shrimp?\u003c\/h3\u003e\n\u003cp\u003eYes. PETG is shrimp-safe (no copper, no leaching) and the smooth interior won't catch moults. The slot join is internal — shrimp can't get caught in it.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it work in saltwater tanks?\u003c\/h3\u003e\n\u003cp\u003eDesigned for freshwater. PETG is inert but we don't currently certify saltwater longevity — for reef and marine setups, source dedicated marine-safe decor.\u003c\/p\u003e\n\n\u003ch3\u003eCan I assemble it outside the tank first?\u003c\/h3\u003e\n\u003cp\u003eNot recommended — the assembled cave is 205mm (Standard) or 272mm (Large), which defeats the purpose of the 2-piece design if you have restricted access. Assemble inside the tank at the corner.\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.
