Morphology | Morphometrics
(total): 4 - 6;
soft rays: 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).
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).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
