Nothobranchius Wattersi

📖 Overview

Nothobranchius wattersi occupies seasonal water pools that are briefly connected owing to seasonal flooding by summer rains and isolated later in the season before eventually desiccating; these pools are characterized by fine black or grey-coloured clay-rich soils typically comprising silt, mud and fine sand, roughly in that order of abundance, and eggs are laid in the uppermost layers of this substratum .

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 17; Anal spines: 0; Anal soft rays: 17 - 18; Vertebrae: 27 - 28. Diagnosis: Nothobranchius wattersi males are similar to N. kirki and differing from all other species of the genus by the following combination of characters: red colouration on caudal fin and part of caudal peduncle, anal fin red with a blue-green proximal portion, dorsal fin with light blue margin; pectoral, caudal and anal fins with black margin . It is readily distinguished from N. kirki by light blue colouration in scale centres, plain deep red colouration on caudal and distal portion of anal fin, vermiculated blue pattern on anal fin, dorsal fin blue-green, anal fin more rounded, dorsal-fin base shorter, prepelvic to preanal distance longer and head longer, with a more flattened to slightly concave shape on the upper head surface relative to N. kirki. : fusiform / normal.
