Body shape (shape guide): fusiform / normal.
Occurs in a typical annual pool with many aquatic plants of the genera Echinodorus, Utricularia, and Nymphaea. The pool has about 800 m length and 300 m width, 1.60 m maximum depth, substrate consisting of clay, and transparent and slightly dark color water. This was the only fish species encountered at the pool, which was shared with many aquatic insect larvae and several tadpole species (Ref. 111470).
