Comments: Sympatric with <i>Tatia intermedia</i> in some rivers in Suriname and French Guiana and also in the Trombetas river (Ref. 79512).  Rather rare, occurs in the slow parts of creeks.  May easily be mistaken as juveniles of <i>Glanidium leopardus</i> with which it is distinguished by means of the pectoral spines (having projections vs. smooth) and by the number of rays in the anal fin (8-9 vs. 12-14).  Sexual dimorphism in males appear at a length of 3.5-4.0 cm.  Its small size makes it interesting for aquarists (Ref. 35381).  Reported sizes at sexual maturity are above 5.46 cm SL and above 7.0 cm SL (Ref. 79512).
