Found in abundance in a shallow lake with depth of less than 1 m. dense emergent vegetation, and abundant grass in the shores. Usually abundant in the roots of dense beds of floating water hyacinth Eichornia crassipes throughout its range. Reproductive cycle occurs in November-March (Ref. 118108). Craig, J.M., L.R.

It can be distinguished from another similar sympatric species G. omarorum by having more anal-fin pterygiophore scales (6-10, mode 8 vs. 5-6, mode 6); more pored lateral-line scales anterior to the first ventral lateral-line ramus (32-47, mode 37 vs. 23-30, mode 27); and fewer ventral lateral-line rami (14-28, mode 22 vs. 28-30, mode 29). It further differs from all other members of the G. carapo clade in having a color patter consisting of 21-29 (mode 28) obliquely-oriented, chocolate-colored bands with wavy, irregular margins and pale interbands less than one-third width of dark bands at mid-body (vs. bands interrupted into patches anterodorsally, with silver, blue or green metallic countershading on dorsum of adults of G. arapaima, dark bands lost in large adults (>25.0 cm) of G. ardilai, small, rounded dark spots over entire body except posterior 20% of some specimens of G. bahianus, bands faint or absent in all specimens of G. chimarrao, one to three inverted Y-shaped dark bands posteriorly and pale bands not reaching above lateral line in anterior two thirds of body of G. choco, bands broken into speckles throughout in G. diamantinensis, narrow pale bands ( Craig, J.M., L.R.
