Setting up a naso tang community tank

Give the group a stable, planted 680 L+ tank with a gentle filter, a reliable heater and plenty of cover — broken sight lines and hiding spots let mid-water and bottom dwellers keep out of each other's way. Cycle it fully and stock gradually.

How to choose

How to choose the right tank mates for a naso tang

Being semi-aggressive, naso tang can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It ranges across the whole water column, so tank mates that keep to one level help reduce friction.

Naso Tang grows to about 45 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 23 cm. Match its water, too: aim for 24–27 °C (75–81 °F), pH 8–8.4 and 8–12 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Naso Tang doesn't need its own kind to feel secure; think twice before keeping more than one if it is territorial. Whatever you add, introduce new fish slowly, watch for bullying in the first days, and have a backup plan if temperaments clash.
