In the above paper, Table 1 was reproduced incorrectly. The corrected table is reproduced below.

- NA, fishes were not counted as the reef was too large and complex to count them accurately.
- a Excluding pomacentrid fishes.
Also, please note that in the abstract the text should read:
The abundance of emerging gnathiids per patch reef was 67 ± 17% of the number of gnathiids that all adult L. dimidiatus per reef eat daily while engaged in cleaning behaviour.
In the Discussion section the text should read: The number of gnathiids emerging per patch reef during the day, and thus potentially available to L. dimidiatus, was 67 ± 17% of the total number of gnathiids that adults ate each day.
When pomacentrids were excluded, the number of emerging gnathiids per fish (20·9 ± 3·8 gnathiids fish−1 day−1) was 4·3 times higher.
Thus, the numbers of gnathiids emerging per fish (4·9 ± 0·8 gnathiids day−1), particularly if they involve the larger gnathiid stages, may be sufficient to kill some young fish recruits and juveniles.
