Conseils de nos experts :

Like most surgeons, the acclimatization of Acanthurus Nigricans is delicate at first glance, because this family- and this species a fortiori- is extremely sensitive to attacks of parasites type cryptocaryon ("white dots") and it is therefore advisable Avoid fish stress so as not to weaken it. Equally usually for this family, once acclimatized to its new environment, Acanthurus Nigricans will rather live its captivity calmly, unless it is confronted with domineering fish. The more it will be stressed, the more it can multiply the episodes of white dots, with a fatal outcome if the fish becomes too weakened.

We therefore recommend maintaining it with smaller species with a passive character. He can accommodate the presence of other surgeons if they are of good company, everyone will tolerate according to a "politeness" protocol which will be specific to the bac.
The ideal will undoubtedly be to spare him such competition, because we emphasize his particular sensitivity, and undoubtedly 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 600 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 thirties, if he is properly nourished and hosted in an adequate space with appropriate roommates.
