Comments: The type locality is a clear water stream with no aquatic vegetation, with average width of 3.1 m and depths of up to 56 during rainy season or 41 cm during dry season, fairly constant water current in the mid-channel, low-speed or still currents observed close to the stream margins or behind plant debirs, average water velocity from 0.44 - 0.76 m/s and water flow between 0.42 m3/s  and 0.74 m3/s, low conductivity (10-11 μS/ cm2), high dissolved oxygen (6.16 mg/L to 7.6 mg/L), low dissolved organic carbon (3.02-3.11 mg/L), and substrate composed mainly of fine white gravel (40-50%), coarse sand (20-40), and leaf litter banks (18-30).  Found in deeper parts of the main channel, mainly over gravel substrate.
