Article Synopsis
- Streams in Sulawesi provide various habitats but lack native freshwater fish due to their isolation within the Wallacea region; however, there are rich diadromous species populations.
- A study sampled 33 streams, capturing 4,632 fish representing 58 species, mostly consisting of amphidromous and euryhaline species, with limited endemism.
- Habitat diversity significantly influences fish community structure, with factors like pH, temperature, and current velocity affecting species distribution and habitat use.
Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges. In Germany, non-native convict cichlids () and tilapia ( sp.) have established populations in the Gillbach, a small stream that receives warm water discharge from a local power plant.

Whereas many tropical fish species have been found in these habitats, the introduction of non-native parasites often remains undetected. Here, n = 77 convict cichlids (Amatitlania nigrofasciata) were sampled by electro-fishing at two sites from a thermally altered stream in Germany and examined for parasite fauna and feeding ecology.
