Setting up a six line wrasse community tank
Give the group a stable, planted 110 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 the right tank mates for a six line wrasse
Being semi-aggressive, six line wrasse 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.
Six Line Wrasse grows to about 8 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 4 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.
Six Line Wrasse 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.
