Husbandry
In contrast to Acanthurus nigricaudus, Acanthurus gahhm is missing the black stripe extending from the tail spine.
Most attempts to keep a pair of black surgeonfish have failed so far.
Needs to be fed 2 to 3 times a day with a diet consisting mainly of macro algae, spirulina, dried sea weed (Nori algae), vegetable flakes soaked with vitamins and some meaty fare.
