Distribution and habitat

The predominantly crepuscular gold dust snails are found exclusively (endemically) in Lake Towuti and the Tominanga River on the island of Sulawesi (Indonesia). There they are found mainly in the shore area but also in greater depths with muddy soft bottoms.

Maintenance

They need a well-structured aquarium with roots, stones and plants. The substrate of sand or fine gravel should be partially covered with foliage (e.g. sea almond leaves, oak leaves), decaying plant material and mulm. Some shaded light and soft to medium hard water is ideal.

Water quality must be that required for average freshwater fish keeping. No ammonia, ammonium or nitrite should be detectable in the water and the nitrate level should be below 100 mg/l. When using a filter, make sure that only a weak current is created and that no animals can be sucked in. The lighting must correspond to the natural day-night rhythm of the animals.

Diet

They feed mainly on dead plant material (detritus) and algae growth, which is rasped off. The food supply consists of foliage, algae leaves, powdered dry food (flakes, tablets) with high vegetable content (spirulina) or a commercially available special dry food, which is well accepted after habituation.

Feeding should be varied to prevent the occurrence of deficiency symptoms. Unaccepted food must be removed after 2-3 hours.

Behaviour and compatibility

They should be kept in a small group of 4-6 animals. Socialization with fish and other invertebrates (shrimp, snails), which do not consider these snails as food, is well possible

Basically, only mutually compatible species with similar requirements for water conditions and water temperature should be socialized.

Reproduction and breeding

They are separately sexual and viviparous. The sexes can not be distinguished from each other externally

After mating, the young snails go through their development in the brood pouch of the female. There the eggs and developing young remain until they are born. The female gives birth to a juvenile every 1-2 months. The young grow up slowly. They can be well raised with dust food for ornamental fish.

Important

Aquatic plants are usually not eaten.

To build up their shells, they need a sufficient supply of lime. Especially in soft, acidic water, shell damage (holes) can occur due to a lack of lime, which can lead to the death of the snail. Therefore, special attention should be paid to the calcium concentration in the water and, if necessary, calcium should be added in the form of limestone, cuttlebone or special preparations from the specialized trade

Foliage (sea almond tree, oak, beech, etc.) not only provides cover, but when rotting promotes the development of microorganisms, which are a valuable secondary food source.

The well-being of the animals should be monitored regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced animals must be accustomed slowly to the water in the aquarium.
