Threespot barb ( Anglèis )

fornì da wikipedia EN

Threespot barb (Enteromius trimaculatus) is a species of cyprinid fish in the large genus Enteromius. It has a wide distribution in sub-Saharan Africa from the Congo Basin east to the Indian Ocean coast of Tanzania and south to KwaZulu Natal in South Africa.[3] It occurs in shallow water around river inflows or near swampy areas. It is a habitat generalist and also hardy, but it prefers vegetated areas. It feeds on insects and other small animals. It is often caught for use as bait by anglers fishing for tigerfish. It breeds during the summer rainy season when shoals of fertile adults migrate upstream when the rivers are in spate following rain. A single females may produce as many as 8,000 eggs.[4]

Barbus trimaculatus ( Italian )

fornì da wikipedia IT

Barbus trimaculatus[2] è un pesce d'acqua dolce appartenente alla famiglia Cyprinidae.

Etimologia

Il nome scientifico in latino, trimaculatus, descrive la particolare livrea a tre macchie nere.

Distribuzione e habitat

Questa specie è originaria del bacino idrografico dello Zambesi, del Lago Malawi e alcuni affluenti, dell'Orange, del Limpopo, e delle acque dolci dell'Africa orientale, dalla Tanzania allo Zambia. Abita ambienti diversi, con acque basse e ricche di vegetazione subacquea, tra i 24-26 °C.

Descrizione

Come tutti i Ciprinidi presenta un corpo lungo ed affusolato, con testa piccola e bocca carnosa e rivolta verso il basso, munita di caratteristici barbigli laterali (2) da cui prende il nome il genere. Il profilo dorsale e quello ventrale sono allungati e arcuati, il peduncolo caudale lungo e piuttosto sottile. La pinna dorsale è alta, triangolare, così come le altre pinne, che presentano però vertici arrotondati. La pinna caudale è bilobata. La livrea vede grosse scaglie argentate, con dorso e fianchi più o meno rosati con riflessi giallastri o verdastri. Lungo i fianchi corrono 3 caratteristici punti neri sulla stessa mediana. Raggiunge una lunghezza massima di 8 cm.

Riproduzione

Simile a quella degli altri Barbus.

Alimentazione

Si nutre prevalentemente di insetti e di zooplancton[3].

Acquariofilia

Non molto conosciuto né tantomeno diffuso in commercio, B. trimaculatus è tuttavia allevato in acquario da appassionati.
