Etymology: Apistogramma: Greek, apisto = uncertain + Greek, gramma = graphic signal (Ref. 45335); paulmuelleri: Named for the late Professor Emeritus Dr. Paul Müller , one of the leading biogeographers of recent decades, who made a number of significant contributions to our understanding of the origins of Neotropical cichlids, including the genus Apistogramma.

Occurs exclusively in a small forest brook. Collected together with Laetacara flavilabris, Crenuchusspilurus, Aequidens sp., three Cichlasoma sp., several medium to adult size specimens of two still undetermined species of Rivulus, and adult specimens of a species of Hyphessobrycon. A few females were observed carrying small fry (Ref. 93321).

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 (0.00397 - 0.03168), b=3.10 (2.86 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
