生態學
; 淡水 底中水層性. 熱帶; 24°C - 26°C (Ref. 2059); 9°S - 15°S
Africa: Endemic to Lake Malawi where it is widely distributed.
非洲: 馬拉威湖的特有種在那裡它廣泛地被分佈。
大小 / 重量 / 年齡
成熟度: Lm ? range ? - ? cm
Max length : 11.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 4996)
背棘 (總數) : 16 - 17; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 9 - 10; 脊椎骨: 31. Resembles P. fenestratus in form and in ecology, but differs from it in having a larger eye and consequently narrower preorbital, in the more numerous teeth in the upper jaw and on the lower pharyngeal, the higher number of gill rakers, the anterior of which, although short, are acute and well defined and in the higher modal number of dorsal spines. Differs from P. virgatus in the absence of enlarged pharyngeal teeth.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
與 P. fenestratus 形式相似與在生態學, 但是在上頜中的眾多齒與在下面的咽骨，較多的鰓耙上不同之處為一個較大的眼與結果比較狹窄的眶前骨前面者那一個, 雖然短, 是尖銳的而且很清晰與在比較高的型背棘數目中。 有別於 P. virgatus 在那缺乏增大的咽齒。
Inhabits shallow, rocky sediment-free habitat. Feeds on 'aufwuchs' attached to rocks, but also takes small invertebrates, including zooplankton when this is abundant (Ref. 267).
棲息於淺灘，岩石的無沉澱物棲息地。 吃被依附於岩石, 也捕食小型無脊椎動物的 '附著生物', 包括浮游動物當這很豐富的時候.(參考文獻 267)

Parents practice co-operative care of young by grouping together and setting up protective stations close to one another; releasing their young and embarking upon parental care. Every protective mantle is very close to the next in such a way that young can move from one parent to the next. 非洲: 馬拉威湖的特有種在那裡它廣泛地被分佈。
