Blubber Cove is a small, family-run UK workshop designing and unique aquarium décor. Every design is crafted from aquarium-safe PETG/PLA, with smooth edges and species-sized entrances for bettas, shrimp, plecos, and nano fish.
Crafted in our UK workshop, these caves blend into your substrate while giving fish and shrimp a safe place to rest, hide, and breed. Each piece is made from aquarium-safe PETG with smooth edges, so your bettas, shrimp, and plecos can use them with confidence. Designed by aquarists, tested in real tanks.
Designed to nestle neatly into tank corners, these natural-style caves create hidden sanctuaries without hogging space. Perfect for fish, shrimp, axolotls, or reptiles seeking shade or solitude, and ideal for aquascapers looking to build beautiful layouts with structure and depth.
Crafted to be buried under your substrate with subtle lip exposure, our under-scape hides offer cosy retreats that feel natural. With arched tunnels and textured surfaces, they encourage natural exploration while letting you reclaim visual space above for plants or hardscape.
Made from non-toxic, aquarium-safe plastic, these caves are built to blend in and last. Suitable for both freshwater and saltwater tanks, they’ve been tested and loved by everything from curious guppies to resting bettas and burrowing reptiles.
