Filicaulis bleekeri is a gastropod without shells which lives as a pest. Meanwhile, F. bleekeri has a potency in waste processing as well as protein source for animal protein livestock. The aim of this study is to investigate the effect of food types such as chinese cabbage, carrots, and green mustard on feeding behavior and growth of F. bleekeri. Observed parameters are preferences, duration, and frequency of feeding, and body weight. The results showed that F. bleekeri favor all parts of the plant that is the center and the edge of the carrot roots, the leaves and base of the leaf of chinese cabbage and green mustard. The highest feeding duration of F. bleekeri was in carrots (92 minutes) and the lowest was in chinese cabbage (48 minutes). The highest feeding frequency of F. bleekeri was also in carrots (average 1.6 times per observation) and the lowest also was in chinese cabbage (average 1.1 time per observation). The average of body weight of big sized F. bleekeri feed to chinese cabbage, carrots, and green mustard are 1.44 g, 1.49 g, and 1.80 g respectively. Body weight gain F. bleekeri small row is 0.82 g, 0.78 g, and 1.14 g respectively. The small sized F. bleekeri showed the highest growth rate.
