Breeding
It spawns in open water, and the larvae drift in the plankton for a long time. It has not been bred in home aquariums, so all fish sold are wild caught.
Good to know
Tinker's butterflyfish is expensive, so check that it is feeding well before you buy. It may pick at some soft corals and invertebrates, so keep it in a fish-only or carefully chosen reef tank. It hybridises with Chaetodon burgessi and Chaetodon flavocoronatus, which look similar.
