Family:	Cichlidae (Cichlids) , subfamily: Cichlasomatinae			picture () by ( not available )
Order:	Perciformes  (perch-likes)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:
Max. size:	12.9 cm SL (male/unsexed; Ref. 74689)
Environment:	benthopelagic
Climate:	tropical
Global Importance:
Resilience:	Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000)
Distribution:	South America: Río Paraná tributaries, Paraguay.
Diagnosis:	Dorsal spines (total): 15-17; Dorsal soft rays (total): 8-10; Anal spines: 6-7; Anal soft rays: 7-8; Vertebrae: 26-26. This species is distinguished by having the largest scales between the dorsal fin and upper lateral line, only 2 ½ scales (vs. 3 ½); similar to A. facetus, cf. facetus, and minuano in coloration patterns. It is the same with forquilha and tembe, in having a small and inconspicuous midlateral blotch and a straight midlateral stripe (if present), running along the flank in the limits of E0 and E1 scale rows; differs with both in having lower meristics, such as 13 caudal vertebrae (vs. 14 or more), a shorter caudal peduncle, shorter scale cover of the dorsal fin, larger (and fewer) scales and a narrower interorbital space (Ref. 74689).
Biology:
