The colours are subject to much variation. In some the back 

 is of a brownish purple ; belly white, with some carmine blotches ; 

 a black longitudinal band on the side, which is broader behind, 

 and does not generally attain the head. On the sides of the latter 

 are two narrow and arched blue lines, which extend from the eye 

 downwards. The fins are brown, marbled with light green ; the 

 spines purple ; the anal, pectorals, and ventrals pink ; the edge 

 of the latter and the rays of the anal orange ; barbels yelloAV ; 

 eye of the same colour, with an external circle orange. In 

 other specimens the colours are lighter, and the back is grey. 

 The adults are a foot long, and are entirely of a beautiful carmine 

 colour, but they always have the black lateral streak and the 

 blue lines of the head. 



It is not very common, but considered one of the best table 

 fishes.
