Ontogeny of stripe formation reveals a rostro-caudal stereotyped pattern. A. ocellaris (a–c′ and g) and A. frenatus (d–f′ and h) color pattern ontogenesis at 8 dph (a-a′, d-d′, A. ocellaris: n = 10; A. frenatus: n = 3), 11 dph (b-b′, e-e′, A. ocellaris: n = 10; A. frenatus: n = 3), 14 dph (c-c′, f-f′, A. ocellaris: n = 10; A. frenatus: n = 3) and 6 months post hatching (g and h, n = 5). Higher magnification of the medial white stripe ontogenesis (a′, b′, c′, d′, e′, f′). Note that the white stripes appear in the same rostral to caudal sequence in both species. Scale bars correspond to 1 mm
