Blubber Cove Coral-Style Aquarium Shelter – Multi-Hole Centrepiece Hide

The Blubber Cove Coral-Style Aquarium Shelter is a sculpted multi-hole hide that sits proudly on top of your substrate as a tank centrepiece. Inspired by Texas holey rock and natural coral formations, the multi-chamber body creates a network of hides, tunnels and grazing surfaces — shrimp colonise the textured exterior, bottom-dwellers claim individual chambers, and cichlid keepers get an affordable alternative to expensive natural holey rock. UK 3D-printed in aquarium-safe PETG.

Why a multi-hole shelter?

Most aquarium caves give one fish one hiding spot. This one gives a whole community their own territory. The multiple holes and internal chambers mean shrimp, corydoras, plecos and shy fish can all use it at the same time without competing — and the open sculptural shape lets water flow through, so detritus doesn't build up inside like it does with closed caves.

How is this different from your aquarium caves?

This is a freestanding sculptural shelter, not a corner cave or buried tunnel. The multi-hole "coral" shape works as a tank centrepiece on top of substrate — and the multiple openings mean a whole community of fish and shrimp can use it at once, rather than one fish claiming a single chamber.

Frequently asked questions

Is it really safe for shrimp?

Yes. PETG is shrimp-safe (no copper, no leaching) and the smooth interior won't catch moults. The multi-chamber design is one of the best shapes for shrimp colonies — every shrimp can find its own grazing surface.

Can I use it instead of real Texas holey rock?

Yes — that's one of the main design intents. Real holey rock is heavy, expensive, and often hard to source. This gives the same visual effect for Lake Malawi setups at a fraction of the weight and cost.

Will fish actually use the holes?

Almost always within 24-48 hours. The 2.5 cm openings are sized for typical community fish — corydoras, small plecos and shrimp all fit through comfortably. Bigger species like adult plecos use the larger chambers.

Does it need to be buried?

No — it's designed to sit visibly on top of substrate as a centrepiece. The open structure means it doesn't need to be hidden to look natural.

Will my African cichlids spawn in it?

The chambers are well-suited for cave-spawning species like apistogramma and kribensis. For larger African cichlids, this works better as territorial cover than a dedicated breeding cave.

Does it work in saltwater tanks?

Designed for freshwater. PETG is inert but we don't currently certify saltwater use — for reef tanks, source dedicated marine-safe decor.

How do I clean it?

The open structure means most debris flushes through naturally during water changes. For algae build-up, use a soft aquarium brush or turkey baster between the holes. Never use soap or detergent.
