Comments: This species is reported from the clear- to black-water rivers of the Upper Madeira where it seems to be scarce in white waters. Inhabits the shallow part of the river near the shores especially where dead woods accumulate and scarce in the running part of rivers.  Apparently common in syntopy with young <i>S. rhombeus</i> individuals of equal size (Ref. 85594).
