Size-related changes in feeding habits of the dwarf loach Kichulchoia brevifasciata were studied by assessing the gut contents in 43 specimens collected between March 2006 and April 2007. The food items showed rapid changes when the fish reached approximately 35-40 mm of standard length. On the basis of the index of the relative importance of the gut contents (IRI), we identified that small individuals mainly fed on the amoebozoa Difflugia and larvae of the aquatic insect Ephemeroptera, while large individuals mainly fed on the diatom algae Navicula and larvae of the insect groups Chironomidae and Trichoptera. The results indicate that a suitable habitat for this highly endangered species has to contain a very diverse community of small benthic invertebrates to allow recruitment across all ontogenetic stages.
