Acanthurus achilles : sensitive fish from Hawaii

Acanthurus achilles

Évitez-lui la concurrence alimentaire, ce serait le mot d'ordre pour éviter les fâcheuses crises de points-blancs, surtout en phase d'acclimatation. Acanthurus achilles est un poisson sensible qui demande du doigté en aquarium récifal, de bon volume (600-800 litres au moins). La présence d'un labre déparasiteur peut faciliter sa maintenance.

Évitez aussi la cohabitation avec des espèces grandes et vives (autres poissons-chirurgiens, grand poisson-ange) qui vont le rendre timoré, au point de ne plus beaucoup sortir de sa cachette. D'ailleurs, lors de l'achat, pensez à son "couchage" : il doit obligatoirement trouver facilement un lieu de refuge en cas de stress et, surtout, pour dormir tranquillement. Une petite grotte, adaptée à sa taille, si possible avec deux entrées l'accueillera facilement, encore faut-il que la place soit libre...

L'alimentation de départ, surtout au cours des premiers jours d'arrivée, est facilitée avec des distributions d'artémias décongelés (ou vivants bien-sûr), sans oublier une importante fraction végétale. L'acclimatation à d'autres nourritures doit se faire assez rapidement après son introduction sous peine de le voir rechigner à s'y adapter par la suite.

Like most surgeons, acclimatization of Acanthurus Achilles is delicate at first glance, because this family is extremely sensitive to attacks of parasites type cryptocaryon ("white dots") and it is therefore necessary to avoid any stress to fish so as not to weaken it. Just as usually for this family, once acclimatized to its new environment, Acanthurus Achilles will undoubtedly become the king of the bac, a little tyrannical with others, but to whom we forgive everything as it is superb!
If he only appreciates the presence of other surgeons, he will be able to accommodate it in the long run, and everyone will tolerate according to a protocol of "politeness" which will be specific to the bac. Even if the clashes will be inevitable, each seeking to take up the upwards on others. We will particularly be careful to acclimatize new arrivals from the same family.

The ideal will undoubtedly be to spare him such competition, because at the price where he sells, no doubt that his healer does not wish to see him injure himself in scalpels or stressed to the point of undergoing cryptocaryon crises ...

The ideal volume of the aquarium will be at least 800 liters: it is not a very large fish, but it likes its ease and it is an excellent swimmer who appreciates speed tips.

We do not recommend his maintenance in aquarium of fish alone (Fish only), because he could see his life expectancy considerably shortened, because of stress. You might as well guarantee it the most beautiful of lives within a mature and well -balanced reef system.
This fish has the very sensitive integument, it is necessary to be careful with mycoses and the erosion of the fins and the side line. Watch out for the quality of the aquarium water, be sure to process bacterial attacks from their first signs and if you use active coal, use only a premium range specific to the marine aquariophilia (dust from The erosion of poor quality coals are recognized for their deleterious action, especially in the damage to the side line).

Remember that this fish is, like all the other fish-surgical fish, a herbivore, even if in captivity it accepts all kinds of meat food with appetite. The surgeons are big eaters because, very dynamic, they spend a lot, and they also have a relatively thick "template" to maintain. This big appetite makes them little eyebrow on the nature of the food source available, although their digestive system in the long run.
To keep this fish healthy and guarantee its longevity, it is necessary to offer it plant foods every day, in the form of fresh or lyophilized algae, or granules for herbivorous fish.

The amount of food available also conditions his "good humor": if he has to fight to eat his hunger, relationships with other aquarium fish will be felt.

His life expectancy can go up to the twenty years, if he is properly nourished and hosted in an adequate space with appropriate roommates.
