Monthly changes in mean (± SE) gonadosomatic index (GSI; dots represent individual values) of Hemiancistrus fuliginosus (a. females; c. males) and Hypostomus isbrueckeri (b. females; d. males). Results of the Kruskal-Wallis tests: Hem. fuliginosus females, H = 47.5, df = 7, p <0.001; males, H = 6.9, df = 7, p <0.44; Hyp. isbrueckeri females, H = 14.4, df = 7, p <0.045, males H = 20.4, df = 7, p <0.005.
