Bioscape Catfish Stone Cave
A resin cave sized for bottom-dwellers to actually use. The Bioscape Catfish Stone Cave is an 8 × 17 × 5 cm resin hide carved with a catfish motif, built to give catfish, plecos and other cave-seeking fish a snug, enclosed spot rather than open decor with no real shelter.
Key features
- True hide, not just decor – the enclosed cave shape gives shy or nocturnal fish somewhere to retreat during the day.
- Resin construction – inert in water, won't affect pH or hardness the way some natural rock can.
- Carved catfish detailing – decorative on the outside, functional on the inside.
- Freshwater and marine safe.

Will it fit my tank?
At 8 cm high and 17 cm long, it suits most standard and nano tanks with room on the substrate for a piece this size. Bioscape doesn't publish a weight figure for this piece, so check it sits stable on your substrate before stocking the tank.
Suitable for, and not suitable for
- Suitable for: freshwater and marine aquariums as a hide for catfish, plecos, cichlids and other cave-dwelling fish.
- Not suitable for: fish too large to comfortably fit the cave opening – check your fish's adult size against the cave's dimensions before buying.
Care and maintenance
Rinse in plain water before adding to the tank. Being resin rather than natural stone, it won't leach tannins or affect pH, and doesn't need soaking or preparation.
Warranty and delivery
Covered by your consumer guarantee rights under Australian Consumer Law if faulty on arrival. Ships as a small parcel.
Common questions
Will this affect my water chemistry?
No – resin decor is inert and won't shift pH, KH or GH the way some natural rock can.
Is it reef safe?
Yes, plain resin decor doesn't affect marine invertebrates or corals.
Does it need to be soaked before use?
No, resin decor can go straight into the tank after a rinse – unlike natural wood or some rock, it won't leach tannins.
