Setting up a mbu puffer community tank
Give the group a stable, planted 757 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 mbu puffer
Mbu Puffer is aggressive and territorial, so most community fish are unsafe; any tank mate must be large, tough and able to hold its own. It ranges across the whole water column, so tank mates that keep to one level help reduce friction.
Mbu Puffer grows to about 67 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 34 cm. Match its water, too: aim for 24–28 °C (75–82 °F), pH 7–7.6 and 5–15 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Mbu Puffer 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.
