With caution

Mango Pleco tank mates that can work with care

  • Adolf's Cory ⚠️ With caution
    Medium care · Peaceful · 5.5 cm · 22–26 °C (72–79 °F)
    Mango Pleco may bully the smaller Adolf's Cory, though its armour makes it a hard meal — give it caves and driftwood to retreat into.

    Medium care · Semi-aggressive · 10 cm · 24–28 °C (75–82 °F)
    pH preferences only just meet (Mango Pleco 5.5–7.5 vs Afra Cichlid 7.8–8.6) — target the overlap and acclimate slowly.

    Adult Amano Shrimp might survive with Mango Pleco, but expect the young to be eaten — plant heavily.

Compatibility is computed from each species' care data — a strong starting point, not a guarantee. Individual temperament varies, so always introduce new fish slowly and watch them.

Setting up a mango pleco community tank

Give the group a stable, planted 265 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 mango pleco

Being semi-aggressive, mango pleco can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It mostly occupies the bottom of the tank, so it pairs naturally with species that use the other levels.

Mango Pleco grows to about 28 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 14 cm. Match its water, too: aim for 25–32 °C (77–90 °F), pH 5.5–7.5 and 2–10 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Mango Pleco 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.
