Dome-shaped houses and shelters, large caves with front entrance or side entrance, smaller tubes, angular shelters, Crusta Caves and Crusta Tubes from Dennerle ... these ceramic hiding places for the aquarium leave nothing to be desired. The natural material clay is formed and then fired.

The resulting ceramic is absolutely neutral in the aquarium water and does not release anything that would increase the water hardness.

These hiding places made of fired clay are extremely robust, durable and stable and offer your aquarium inhabitants such as catfish and small, still young as well as large, adult crayfish reliable protection from conspecifics, a spawning cave or a place where a freshly skinned crayfish can recover in peace and let its shell harden. Egg-bearing female crayfish also need a place where they can find refuge and hide well from their conspecifics.

The slightly rough surface of natural clay creates a huge surface area where beneficial bacteria can colonize and break down urea, nitrite, ammonium and ammonia in aquarium water, improving water quality and breaking down pollutants. The more surface area, the more bacteria can do this important work.

Most of the ceramic hiding places you can buy in this category are carefully handcrafted in Germany. So these useful decorative items for the aquarium are mostly real unique specimens. The finely embossed and patterned surface not only offers the above-mentioned pollutant-degrading filter bacteria really a lot of space, it also ensures that the hiding places look very natural and do not stand out too much in the aquarium. Of course, they can still be draped as an eye-catcher in an appropriate aquarium setup and cut a really good figure even then.
