Mean number of symbionts per individual host (Briareum asbestinum) recruits in the (a) absence and (b) presence of competition. Low‐light (gray) and high‐light (gold) treatments at 6 weeks (left panel) and at 8 weeks (right panel) following initial inoculation of newly settled recruits. Symbiodinium microadriaticum (S. mic.), Breviolum minutum (B. min), Durusdinium trenchii (D. tren.). Data were log transformed, the geometric mean calculated and back transformed. Error bars represent back transformed 95% confidence intervals. An ANOVA indicated a significant effect of light (small letters) and symbiont (large letters) treatments on symbiont densities within the 6‐week treatment. No significant difference was observed within the 8‐week treatment
