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.
but differs in colour and morphometrics.
