Bring the diverse and unique aquatic ecosystems of the Great Rift Lakes of Africa to your aquarium with the Nautilus Tan River Kit. This all-in-one kit includes a carefully curated mix of warm-toned substrate, distinctive perforated stones, and nutrient-rich plant substrate — perfect for recreating biotopes of African lakes, estuarine, and rocky shoreline environments.
At the heart of the Nautilus Tan kit is the Hole Stone — a unique sedimentary rock with warm, gritty tones and distinctive natural perforations of varying sizes that create functional caves and shelters for cichlids and other lake-dwelling species, while providing perfect anchoring points for epiphytic plants. The kit includes a full range of Hole Stone sizes from XL down to small, alongside a 2 kg bag of Hole Nano Rocks for foreground detail and intricate rock formations. The warm Artist Mustard plant substrate — a 5 kg nutrient-rich growing medium — provides a natural sandy-gold foundation that evokes the sun-baked lakebeds of East Africa, while the Nautilus Tan Biotope Beds add authentic fine substrate character.
The result is a warm, textured, cave-rich landscape perfect for African cichlid biotopes, rocky lake shorelines, or any layout that calls for natural sheltering structures and a warm, sunlit aesthetic.
