There is very little that is known on the ecology and habitat of this species, for only six specimens exist in collections. Specimens from Rio Pomba (MCP 27296 and MCP 31467) were collected during the night in the main river channel, on a rocky bottom and in a very strong current (Ref. 57859).

= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this BS (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
