Can Apistogramma Broad-banded and Purple Spotted Gudgeon Live Together?
Apistogramma Broad-banded and Purple Spotted Gudgeon are not recommended as tank mates due to incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Apistogramma Broad-banded and Purple Spotted Gudgeon?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Both Apistogramma Broad-banded and Purple Spotted Gudgeon are moderately assertive species with an aggression score of 5/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Apistogramma Broad-banded and Purple Spotted Gudgeon both frequent the Bottom (Substrate) and Middle (Open Water) 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: Two territorial species may clash over territory, especially in smaller tanks.
Worth noting: Purple Spotted Gudgeon is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Apistogramma Broad-banded needs 1–5 dGH while Purple Spotted Gudgeon requires 8–20 dGH.

Tank Setup
To house Apistogramma Broad-banded and Purple Spotted Gudgeon together, plan for an aquarium of at least 83 litres with a minimum length of 60 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
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, 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.

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma Broad-banded and Purple Spotted Gudgeon need?
A minimum of 83 litres (tank length at least 60 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Apistogramma Broad-banded and Purple Spotted Gudgeon together?
Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.
Are Apistogramma Broad-banded or Purple Spotted Gudgeon aggressive?
Apistogramma Broad-banded is moderately assertive (5/10) and Purple Spotted Gudgeon is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Apistogramma Broad-banded and Purple Spotted Gudgeon need?
Both species overlap in the 6.5–6.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Apistogramma Broad-banded's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma Broad-banded space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
