| Grouper are close to the top of the fish food chain, anthias and damselfish near the bottom, so there must be smaller fish somewhere. |
| In the open water just off the reef, great swarms of damselfish cavorted, collecting plankton while barracuda cruised by trying to select an easy meal. |
| Up to 25 percent of all fish on reefs are cardinalfish, and damselfish compose up to 50 percent of the total fish biomass on reefs, the study says. |
| Because both cleaners and damselfish are diurnal, cleaning activities only occur during daylight periods. |
| Dorsey chose to work with the bicolor damselfish because they are not considered a threatened or endangered species. |
| Many small fish, including juvenile fairy basslets and damselfish, retreat into crinoid arms when bigger fish appear. |
