Each of these caves is unique since they were created as prototypes during the development of a new range of Biohome Caves (which will be available from June 2026). 

We're selling the prototypes off for the cost of the filter media and they will have a positive filtering effect in the tank as they support aerobic and anaerobic bacteria for the reduction of ammonia, nitrite and nitrate.

BOOST TANK FILTRATION

PROVIDE HABITAT / BREEDING SPACES FOR PLECS, CICHLIDS AND SHRIMPS

PLANT UP THE CAVES WITH JAVA FERN / JAVA MOSS / ANUBIAS FOR AN EVEN MORE NATURAL LOOK
