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.

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.
