Remarks Feeds exclusively and frequently on large numbers of eggs of small fishes such as damselfish, blennies and gobies. Moves slowly and continuously across crevices and burrows while hunting for fish nests. Only active during daylight. Locates its prey via smell rather than through visual cues (Ref. 101738).
