Hybrid vs parents in foraging little fish or periphytic algae. a Small fish (S. taeniatus). b Rock with tender periphytic algae (Spirogyra). c PS vs SW in the FAT (first attack time). d PS vs SW in the AF (attack frequency). e PS vs SW in the foraging level. f PS vs SW in the FE (foraging efficiency). g PS vs PP in the SRFC (success rate of the first successful capture), SRTA (success rate of the total attacks) and SR (spitting rate). h PS vs PP in the FAT, FST (first success time) and FAT2 (first attack time after the first successful capture). i PS vs PP in the AF (attack frequency). The scale is 1 mm. The numbers above the columns give the P-value based on Tukey test, the height give the mean, the thick lines give the medians and whiskers indicate mean ± SE
