This mixed-effects model revealed a highly significant effect of year on group size ( p < 0.001), with no significant effect of reef or a year × reef interaction (Supplementary Table 3 , Supplementary Table 4 ).

Our second analysis focusing on anemone survival revealed a significant decline in anemone survival in 2023-2024 (Firth logistic regression: β = –8.44 ± 1.91, p < 0.0001; Supplementary Table 2 ), and a marginally significant decline in anemone survival with increasing anemonefish group size (Firth logistic regression: β = –1.20 ± 0.69, p = 0.053; Supplementary Table 3 ).
