Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 14 - 15; Rückenflossenweichstrahlen (insgesamt) : 13 - 14; Afterflossenweichstrahlen: 7; Wirbelzahl: 28. Diagnosis: upper lateral line extending full length of dorsal fin base and descending a row before proceeding the length of 3 or more scales; 15 gill-rakers along lower limb of first arch; 35-37 lateral line scales; relatively large headed and deep bodied; pectoral fin long, usually extending to level of spinous anal fin (Ref. 52346).
Omnivorous, prefers small organic particles, regardless whether they are plants or small insects (Ref. 52307). Opportunistic bentic microphage; probably tolerant of relatively high salinity levels (Ref. 52346). Maternal mouthbrooder (Ref. 52307, 52346) that does not pair bond (Ref. 52307).
