The Spotted Peacock Bass is painted black from the top of it's head to its tail. Half of it's tail is black but only the top of the rest of the fish is black.
It's sides are a muted yellow that fades to orange with the bottom half of it's tail being orange along with it's anal, pectoral and pelvic fins. Several black vertical bars travel down from it's back and fading to it's belly. However, what is unique about this spotted bass are the spots on its head and tail. the spotted lines that run horizontally along its sides and across its dorsal fins. Though once considered a separate subspecies of the Peacock Bass, it is now classified as the same species as the Speckled Peacock Bass but with different paintings.
The Spotted Peacock Bass shares the largest of the peacock/pavon species attribute with the Speckled Peacock Bass as it can grow up to a three feet, four inches in length. It is slightly elongate with a large head, and it looks more like a bass than the other peacock subspecies.
There is some orange on the tail under the eye spot but the rest of the speckled peacock bass is dark to yellow down the side and white on the underside of the fish.
It has three dark vertical bars and a series of horizontal rows of cream, coloured spots and during spawning, the males acquire a nuchal hump during spawning.
A common characteristic shared by all peacocks is the black circular eye spot. In the Spotted Peacock, the eyespot is rimmed in white, which is stark compared to the overall black in the top half of the tail where it is located. This spot closely resembles the tail plume of a peacock fowl. Hence, the name peacock bass became the perfect moniker.
The Spotted Peacock Bass and Speckled Peacock Bass attains the greatest size of all peacock bass with the largest one on record being a 28 pound peacock, though this record is expected to be a temporary record with some many fish being caught in the mid 20 pound range. The normal expected adult size is ten pounds, but those exceeding this weight are common in some areas.
The Spotted Peacock Bass has reportedly a fairly uniform, continuous growth rate until it dies of old age. The average size of most peacock bass is around three or four pounds, but in many South American waters, several between six and 10 pounds may be taken on a good day and in a few select places, monsters over 15 pounds can be caught occasionally.
The Spotted Peacock Bass is also the largest of the species in terms of the length that it can achieve with the record speckled peacock bass reaching three feet, four inches in length.
