The wide curved entrance lets bottom-dwellers glide in and out without snagging fins or whiskers, while the flat top sits neatly at the front of your aquascape — or buries seamlessly under sand or gravel for a natural underground-cave look. UK 3D-printed from aquarium-safe PETG. No glue, no paint, no sharp edges.\u003c\/p\u003e\n\n\u003ch2\u003eWhy bottom-dwellers need a cave tunnel\u003c\/h2\u003e\n\u003cp\u003ePlecos and corydoras are nocturnal foragers — they need a dark, low shelter during daylight hours to feel secure. Without one, they hide behind filters, wedge themselves under driftwood, or stop eating. A purpose-built pleco cave tunnel gives them a stress-free daytime retreat and a defined territory, which reduces aggression in shared tanks.\u003c\/p\u003e\n\n\u003ch2\u003eThree ways to use it\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForeground feature:\u003c\/strong\u003e sit it at the front of the tank as a visible cave — low profile means it doesn't block view lines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnder sand:\u003c\/strong\u003e bury it under your substrate so only the entrance shows — creates an underground-cave effect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnder gravel:\u003c\/strong\u003e partially submerge in gravel for a natural rock-overhang look\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eLarge curved entrance — sized for adult plecos (up to 15cm body length on the Large)\u003c\/li\u003e\n  \u003cli\u003eLow foreground profile — won't dominate the aquascape\u003c\/li\u003e\n  \u003cli\u003eHollow tunnel design — fish enter one end, exit the other\u003c\/li\u003e\n  \u003cli\u003eWorks under sand, gravel, or as a visible foreground feature\u003c\/li\u003e\n  \u003cli\u003eSmooth snag-free edges — safe with 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\u003eNo glue, no paint, no leaching — inert in freshwater\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 130 × 130 × 75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge size:\u003c\/strong\u003e 230 × 155 × 70 mm\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\u003eBristlenose plecos, common plecos, clown plecos\u003c\/li\u003e\n  \u003cli\u003eCorydoras (all species — pygmaeus, panda, bronze, sterbai)\u003c\/li\u003e\n  \u003cli\u003eKuhli loaches and weather loaches\u003c\/li\u003e\n  \u003cli\u003eNeocaridina and Caridina shrimp\u003c\/li\u003e\n  \u003cli\u003eOtocinclus, hillstream loach, whiptail catfish\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 (130 × 130 × 75 mm):\u003c\/strong\u003e nano tanks 20–60 litres, bristlenose plecos under 10cm, shrimp colonies, corydoras\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge (230 × 155 × 70 mm):\u003c\/strong\u003e mid-size tanks 60–250 litres, adult plecos, clown loaches, multiple bottom-dwellers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3\u003eWill my pleco actually use it?\u003c\/h3\u003e\n\u003cp\u003ePlecos almost always claim a cave within 24-48 hours. They're territorial and prefer enclosed daytime shelters. If your pleco doesn't use it immediately, place it in a quieter corner of the tank away from filter outflow.\u003c\/p\u003e\n\n\u003ch3\u003eCan I bury it under sand or gravel?\u003c\/h3\u003e\n\u003cp\u003eYes — that's one of the main design intents. Bury the top and sides so only the entrance shows. It creates an underground-cave effect and looks completely natural in planted setups.\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). The smooth edges won't catch shrimp moults, and the tunnel form gives them a foraging and shelter zone away from larger tankmates.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit my tank?\u003c\/h3\u003e\n\u003cp\u003eThe Standard fits nano tanks from 20 litres. The Large suits tanks from 60 litres up. If you have a Fluval Spec, Flex, or other small tank, choose the Standard.\u003c\/p\u003e\n\n\u003ch3\u003eHow is this different from your other aquarium caves?\u003c\/h3\u003e\n\u003cp\u003eThis is the \u003cstrong\u003etunnel\u003c\/strong\u003e version — long, low, with two openings, designed to sit at the front or buried under substrate. Our rounded hideaway cave is a single-entrance dome shape for mid-tank placement. Our corner caves fit into 90-degree tank corners.
