“…Therefore, it has received an intensive interest from scientists of various fields for decades (e.g., Rahmouni et al, 2018;Kmentová et al, 2018;Koblmüller et al, 2019;Ryan et al, 2020;Ivory et al, 2021). In this respect, cichlids (Cichlidae) have become one of the most studied model systems in the research on evolutionary processes, speciation events (e.g., Hayward et al, 2017;Irisarri et al, 2018;Fischer et al, 2021), and behavioural biology (e.g., Raffini et al, 2018;Satoh et al, 2019Satoh et al, , 2022. Currently, 240 valid cichlid species belonging to 52 genera and 13 tribes are described from Lake Tanganyika; all (except two species) are endemic to the basin (Ronco et al, 2021) and comprise the morphologically, behaviourally, and ecologically most diverse species assemblage (Snoeks, 2000).…”
