Can Agassiz's Dwarf Cichlid and Mbu Puffer Live Together?

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Mbu Puffer is semi-aggressive (7/10). This modest difference means Mbu Puffer may occasionally assert dominance over Agassiz's Dwarf Cichlid.

Agassiz's Dwarf Cichlid and Mbu Puffer both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Mbu Puffer requires 10–25 dGH. An aquarium test kit is recommended for monitoring.

To house Agassiz's Dwarf Cichlid and Mbu Puffer together, plan for an aquarium of at least 1800 litres with a minimum length of 240 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Feeding time deserves special attention with this pairing. Mbu Puffer is an aggressive eater that may prevent Agassiz's Dwarf Cichlid from getting enough food.

Because Mbu Puffer is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Agassiz's Dwarf Cichlid receives an adequate share.
