Info
Information on the wrasse Thalassoma heiseri is extremely sparse and photos of live animals are almost impossible to find online.
The distribution of the species is (was?) restricted to the Pitcairn Islands and the Tuamotu Archipelago in French Polynesia.
The species was described in 1984, the IUCN Red List of Threatened Species gives the status "Least concern" and the note "needs updating".
Whether this wrasse species still exists today remains an open question in our view; even the comprehensive work "Guide des poissons de Tahiti et ses Îles" does not deal with Thalassoma heiseri.
The same applies to the volume on wrasses "Labridae Fishes: Wrasses" by Rudie Herrmann Kuiter.
The literature is similarly vague when it comes to the habitat of the wrasse, stating that the species "probably lives in rocky reefs and perhaps also in coral reefs".
So one thing is certain: Thalassoma heiseri will certainly never swim in any aquarium!
Synonym: Zyrichthys heiseri Randall & Edwards, 1984
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
