Relevant Information:

Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 5. Distinguished from all other species of the genus Harttia except Harttia tuna and Harttia trombetensis by having an incomplete abdominal cover, restricted to preanal and abdominal lateral plates with a row of platelets joining these two series of plates (vs. absence of row of platelets making junction between preanal and lateral abdominal plates), and by its specific barcode sequence (JF292263). Differs from Harttia tuna by having a deeper head (37.31-43.30, mean 38.94 ± 1.42% of HL, vs 31.96-38.77, mean 36.52 ± 1.80% of HL), and from Harttia trombetensis by its colour pattern of caudal fin (a large dark band at base of caudal fin vs. a dark rounded blotch). Can be further diagnosed from all other congeners by having a greater minimum caudal peduncle depth (mean = 1.60 ± 0.11% of SL vs. 1.35 ± 0.13 < mean < 1.43 ±0.11% of SL); and a greater interorbital width (mean = 24.25 ±1.02% of HL vs. 22.04 ± 1.27 < mean < 23.12 ± 1.11% of HL). Aquarium Care: Not the easiest genera to keep as they will need clean, oxygen rich water and a strong current. Does not do well in imports due to its difficulty in traveling containers. Diet: Dry foods, algae wafers, Spirulina and normal tablet foods. Frozen foods, Artemia nauplii, glass worms and Daphnia. Sexual Differences: Males tend to have odontodes (hair like structures) on the first ray of the pectoral fins and the head in males is broader. Remarks: similar to H. surinamensis but differs in colour and morphometrics.

Common Name:







South America: Known only from the Coppename River drainage in Suriname.
