Melanotaeniidae (Rainbowfishes, blue eyes)
Etymology: Melanotaenia: Greek, melan, -anos = black + latin, taenia = stripe (Ref. 45335); senckenbergiana: Presumably named for the Senckenberg Museum of Frankfurt, Germany, publisher of the journal where the original description of this fish first appeared (Ref. 110723).
Eponymy: Probably named for the Senckenberg Museum, Frankfurt, Germany (the original description was published in the museum journal: Abhandlungen der Senckenbergischen Naturforschenden Gesellschaft) rather than directly after Johann Christian Senckenberg [...] (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 4 - 6; Dorsale zachte stralen (totaal) : 11 - 15; Anale stekels: 1; Anale zachte stralen: 20 - 23. Melanotaenia senckenbergianus is distinguished by the following combination of characters: IV-VI-I,11-15 (usually VVI- I,12-13) dorsal-fin rays; I,20-23 (rarely 23) anal-fin rays; 13-15 (usually 14) pectoral-fin rays; 34-36 scales on lateral line; 16-19 (rarely 19) predorsal scales; 15-24 (average 19.6) cheek scales; 17-18 total gill rakers on first arch; greatest body depth of adult male 35.9 % SL; color in life generally greenish brown dorsally, grading to silvery white to pale yellow ventrally
with midlateral, dark blue stripe, 1-2 scale rows wide, extending from rear margin of eye to caudalfin
base, usually faint or interrupted on middle of side; operculum with prominent red spot, smaller
than pupil (Ref. 110723).
Body shape (shape guide): fusiform / normal.
Inhabits creeks and small rivers flowing through primary rainforest and second growth forest and gardens, as well as tree-lined creeks in relatively open savannah. Syntopic with either Melanotaenia albimarginata, M. aruensis, or M. patoti as well as other fishes such as Craterocephalus, Mogurnda, Glossamia, and Glossogobius (Ref. 110723).
