Richard Bailey and Brian Cole (Aquaculture Extension Agents, Sea Grant Extension Service, School of Ocean and Earth Science and Technology, University of Hawaii) have published a report documenting techniques for spawning the tinfoil barb. The report is available as a free download (.pdf) from the Center for Tropical and Subtropical Aquaculture. It is entitled: CTSA #136. Bailey, R. and B. Cole. 1999. Spawning the Tinfoil Barb, Barbodes schwanenfeldi, in Hawaii. 8 pp.
From the report:
The tinfoil barb, Barbodes schwanenfeldi, is a common fish found in the international aquarium trade and food markets in Southeast Asia. Tinfoil barbs are a peaceful fish that can reach a length greater than 40 centimeters or 16 inches, and like other, larger barbs, can often live more than 10 years in captivity. In nature, tinfoil barbs are primarily macrophages; that is, they feed on vascular aquatic plants. However, they will eat most commercially prepared diets consisting of vegetable and fish meal proteins.
