There are several potential reasons why your Tanganyika gold cichlids may not be eating. It could be due to stress from changes in their environment, water quality issues, illness or disease, or simply not liking the food being offered. It's important to check the water parameters, ensure the tank is properly cycled, and offer a variety of high-quality foods to entice them to eat. If the issue persists, it may be necessary to consult with a veterinarian or experienced fish keeper for further assistance. **

Yes, Lake Tanganyika is home to a variety of freshwater mussels and snails. The lake's diverse ecosystem provides a suitable habitat for these species to thrive. Mussels and snails play important roles in the lake's food web and contribute to its overall biodiversity. **

The species diversity in cichlids in Lake Tanganyika has arisen through allopatric speciation, which occurs when a population is geographically isolated and evolves separately from the original population. In the case of Lake Tanganyika, the lake's complex and varied habitat has led to the formation of different isolated populations of cichlids. Over time, these isolated populations have evolved unique traits and characteristics, leading to the formation of new species. The geographical isolation and the diverse ecological niches within the lake have allowed for the rapid diversification of cichlids through allopatric speciation. **

For a Tanganyika aquarium with shell-dwelling cichlids, it is optimal to use a fine to medium grain size of sand gravel. This type of substrate closely mimics the natural habitat of these cichlids, as they are used to living in sandy bottoms with scattered shells. The fine to medium grain size allows the cichlids to easily sift through the substrate to create and maintain their territories and also helps to prevent the shells from shifting around too much. Overall, a fine to medium grain size of sand gravel provides a suitable and natural substrate for shell-dwelling cichlids in a Tanganyika aquarium. **
