Tropical freshwater mussel, Pilsbryconcha exilis

The pretty medium-sized Tropical Freshwater Mussel Pilsbryoconcha exilis is widely distributed throughout Southeast Asia. It occurs in quite different habitats and is quite adaptable and robust. Its yellow to brownish shell is elongated and reaches a size of up to 10 cm. Beside the vertebra Pilsbryoconcha exilis often has a typical corner. In its habitat it is very popular as a food mussel. The Tropical Freshwater Mussel is a relatively persistent aquarium inhabitant, if it is fed sufficiently, with the right food and above all regularly.

In order for the larvae of the Tropical Freshwater Mussel to develop, they must attach themselves to the gills of very specific host fish. Without these fish, they die. They also do not randomly infest any fish. Therefore, in the aquarium, reproduction of Pilsbryoconcha exilis is practically impossible.

The Tropical Freshwater Mussel depends on a good water current that constantly flushes food within its reach. It does not feel very comfortable in an overly clean aquarium. Mussels filter suspended solids from the water, using their siphon to draw in the water and sift it inside. The clean water is then expelled again.
Filterless aquariums are good for keeping the Tropical Freshwater Mussel, as long as they are equipped with a flow pump to keep the water moving slightly. Filtered aquariums are usually too clean for mussels.
Large clams such as Pilsbryoconcha exilis should therefore generally be fed a special clam food once or twice a day that is tailored to their needs. During and even for a while after feeding, it is advisable to turn off the filter. For feeding it is recommended to use a pipette - this way you can get the food close to the mussel without disturbing it too much.

A relatively thick layer of sand or fine gravel should always be present in the aquarium, as the Tropical Freshwater Mussel likes to burrow.

Pilsbryoconcha exilis, the Tropical Freshwater Mussel, is very well suited for socialization with common ornamental fish, but it can also be kept together with snails or dwarf shrimps, possibly also dwarf crabs and also with other mussels . Ideal is the keeping with fan shrimps.

The Tropical Freshwater Mussel needs a temperature of 20 to 28 °C and prefers harder water than too soft. A pH of 7 to 8 and a GH of up to 20 are recommended.
