↵* VBL, Neochromis “velvet black”/“blue scraper”.
↵† Maximum depth is the depth of the deepest point within 100 m around each station and a measure of the time for which the area around each station is flooded again after the desiccation of the lake.
↵‡ T_{400 nm}, transmission at 400 nm; T_{580 nm}, transmission at 580 nm.
↵§ Nyererei complex is an undescribed genus (7, 33).
