Blubber Cove Skull Aquarium Cave – Gothic Fish Tank Decor & Shrimp Hide

The Blubber Cove Skull Aquarium Cave is a sculpted skull-shaped hide for aquascapers who want their tank decor to double as a focal point. Designed for gothic, fantasy and Halloween-themed aquariums — made the same way as the rest of our cave range. Smooth interior, snag-free edges, precision-manufactured in the UK from PETG.

Gothic decor built for permanent tank use

Most novelty fish tank decor is painted resin imported in bulk. This skull cave is sculpted from solid PETG with no paint, no glue, and no surface treatments. Suitable for permanent tank use, not just seasonal.

Frequently asked questions

Is it a working hide or just a decoration?

Both — it's a working hide. The interior is smooth and rounded so fins won't snag, and there's no paint or dye on it.

Can I leave it in the tank permanently?

Yes. It's designed for permanent use, not just seasonal display. The PETG won't degrade in water and the print is structurally solid.

Will my betta or shrimp actually use it?

Yes — bettas love enclosed hides for resting, and shrimp colonise the textured surfaces for grazing. The skull's eye sockets and mouth opening give multiple entry points so fish can swim through.

Is it suitable for a Halloween tank?

Yes — it's a popular choice for October/November themed setups. Unlike cheap seasonal decor, it's built for permanent use afterwards, so you're not throwing it out in November.

Does it work in a planted tank?

Yes. Pair with java fern, anubias, cryptocoryne and dark substrate for full gothic-aquascape effect. The white skull contrasts beautifully against dark planted backgrounds.

How do I clean it?

Rinse in tank water during your weekly water change. For algae build-up, use an aquarium-safe brush. Never use soap, detergent or bleach — soap residue can harm fish.
