The GlasGarten Crispy Caves are edible tubes and caves made from 100% natural ingredients – simultaneously food, a hiding place, and a biofilm reactor. They consist largely of wood fibers (cellulose), clay, and leaves – precisely the materials found in the natural habitats of shrimp, snails, and crayfish. The dietary fibers actively scrape off nutrients such as algae and bacteria from the biofilm, which corresponds to natural feeding behavior.

Why Crispy Caves are so special:

• Food & Hiding Place in One: The cave offers smaller animals protection and a quiet feeding spot – they can nibble on the wall from the inside, while larger animals eat from the outside.
• Important Dietary Fibers: Wood fibers (cellulose) are essential for shrimp, snails, and suckermouth catfish – they promote digestion and are a firm component of their natural diet.
• Natural Biofilm Formation: The rough surface provides an ideal hold for microorganisms – the resulting biofilm is a constant, protein-rich food source around the clock.
• Dimensionally Stable & Water Neutral: The Crispy Caves do not pollute the water and can remain in the aquarium permanently until they are completely eaten.
• Suitable for Many Animals: Shrimp, snails, suckermouth catfish, crayfish, and land crabs – also ideal as holiday or vacation food.
