After spawning within a community setting, eggs were removed from the females’ mouths and females (n = 84) were transferred to the central compartment of a 200- l rectangular observational arena divided into three sections by transparent and perforated dividers (Fig. 1). Premature cessation of the normal 15-day oral gestation period results in an instant acceleration of vitellogenesis [57] and subsequent ovulation within 28–30 days [34]. Within these experimental tanks, females were exposed to visual and olfactory cues from ‘‘attractive’’ (large: >7 cm standard length; brightly colored) and ‘‘less attractive’’ (small:
