Larval food habits of the forest green tree frog (Rhacophorus arboreus) were studied in the laboratory. Tadpoles were fed single food items (leaf litter, algae or sludgeworms) individually, and their survival, growth, and development were compared. All of the algae-fed and 38% of the worm-fed tadpoles metamorphosed, but none of the litter-fed tadpoles did. Algae-fed tadpoles developed faster than wormfed ones and their size at metamorphosis was the same. Algae are the most suitable food item for the larvae of Rhacophorus arboreus.
