Can Apistogramma Orange-tail and Butterfly Goodeid Live Together?
Apistogramma Orange-tail and Butterfly Goodeid 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 Orange-tail and Butterfly Goodeid?
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
Apistogramma Orange-tail is a moderately assertive species (5/10), while Butterfly Goodeid is moderately assertive (6/10). This modest difference means Butterfly Goodeid may occasionally assert dominance over Apistogramma Orange-tail.
Apistogramma Orange-tail and Butterfly Goodeid both frequent the 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.
Water Parameters
The safe temperature window for both species falls between 23°C and 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Apistogramma Orange-tail needs 1–8 dGH while Butterfly Goodeid requires 10–25 dGH.
Tank Setup
To house Apistogramma Orange-tail and Butterfly Goodeid together, plan for an aquarium of at least 110 litres with a minimum length of 80 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, Established Algae (Otocinclus), Plants - lighly covered. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Butterfly Goodeid is a plant destroyer, which conflicts with Apistogramma Orange-tail's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Usually Fails in Practice
Apistogramma Orange-tail and Butterfly Goodeid are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Frequently Asked Questions
Can Apistogramma Orange-tail and Butterfly Goodeid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma Orange-tail and Butterfly Goodeid need?
A minimum of 110 litres (tank length at least 80 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 Orange-tail and Butterfly Goodeid together?
Keep the aquarium between 23°C and 26°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are Apistogramma Orange-tail or Butterfly Goodeid aggressive?
Apistogramma Orange-tail is moderately assertive (5/10) and Butterfly Goodeid is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Apistogramma Orange-tail and Butterfly Goodeid need?
Both species overlap in the 7–7.2 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Butterfly Goodeid nip Apistogramma Orange-tail's fins?
Butterfly Goodeid is a known fin nipper. If Apistogramma Orange-tail has long or flowing fins, there is a real risk of fin damage. Keeping Butterfly Goodeid in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Apistogramma Orange-tail's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma Orange-tail 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.
