Randall, 1955

A very beautiful surgeonfish which almost completely changes its colour when it matures. Juveniles have a bright orange coloured body and head with variegated bright violet and blueish lines, radiating in a kind of herringbone pattern. The fins are tinged violet and become bright blue posteriorly, just above and below the caudal peduncle.
Characteristic for the Chevron tang, as for the other species of the Ctenochaetus genus, are the protrusive pouting mouth including several rows of flexible comb like teeth. These are adapted for scrubbing off short algae and detritus off rocks, sand and other surfaces, then the tang uses its mouth to suck the food up. If you intend to keep a Chevron tang in your aquarium you should give credit to its habit of feeding by adding plenty of live rock. It is a constant grazer and will spend most of the time picking at rocks and sand, nevertheless for its well-being it also needs supplementary food including nori algae, spirulina algae and frozen food e.g. mysid shrimps. As an active swimmer it requires ample of swimming place.

In general the Chevron tang makes a peaceful companion for other tank mates.

Dieser schöne Doktor bereichert seit ca. 1,5 Jahren unser Becken. Habe ihn mit ca. 8cm Größe futterfest gekauft. Absolut friedlicher Geselle, der nur ab und zu mal seine Kräfte mit unserem flavescens mißt (andere Doktoren sind nicht vorhanden). Ist innerhalb eines Jahres gut gewachsen, wobei ich jetzt den Eindruck habe, dass er größenmässig stagniert - bei ca. 13 bis max. 15cm. Fühlt sich bis jetzt in 500l (Riffaufbau mittig, mit Bogen in der Mitte) durch sehr abwechlungsreichen Aufbau scheinbar nicht beengt (da keinerlei Anzeichen von Hospitalismus). Frisst bei mir alles, was man hinein wirft und knabbert dennoch täglich das komplette LG nach Algen ab. Scheiben lutscht er bei mir nicht ab und Kieselalgen habe ich ihn auch nicht fressen sehen. Toller Doktor; eine Bereicherung fürs Becken!

The juvenile Chevron Tang is relatively easy to acclimate to the home aquarium. It just takes some time to get it through the adjustment period.

A subtley beautiful and brilliantly colored fish when healthy and well acclimated. It takes attention and a willingness to provide it with what it needs to survive.

Because it is reclusive and avoids (rightly so!) humans, the fish must start off in a quarantine tank where it must confront the human and learn: not to fear humans; that humans provide food; and aquarium life is a good life. Quarantine provides the safety and security the fish needs after traveling from so far away. It gives time for it to learn to eat available foods, and to fatten up and be ready to enter the display tank. Also, since tangs attract Marine Ich and Marine Velvet, the quarantine is a fine opportunity to make sure it is healthy.

Provide algae daily, whether it eats it or not. Try frozen pods (mysis and brine shrimp). If these don't tempt it, try living foods (brine shrimp and mysis (bahia)).

Spend a lot of time in front of the fish, making no sudden or threatening moves. The patient aquarist is rewarded with a very comfortable and healthy pet.

Ich kann mich eigentlich nur auf den Standardtext beziehen. Dieser Doktor ist klein (siehe Bild) sehr schön anzusehen, wird aber mit (und das geht schnell) meist braun von der Färbung her. Nichts desto trotz ein interessaner Doktor der mehr als 1000 Liter Wasser haben sollte. Er wird schnell gross und schwimmt viel. Er fühlt sich in 1000 Liter nach einer gewissen Weil nicht mehr wohl, zumindest hatten wir den Eindruck. Es kam dann zu den schon beschriebenen Übergriffen. Wie alle Ctenochaetus Doks lutschen sie bevorzugt Algen von der Scheibe,. sprich auch Kieselalgen.
