Can Amazon Leaf Fish and Violet Goby (Dragon Goby) Live Together?
Amazon Leaf Fish and Violet Goby (Dragon Goby) are not recommended as tank mates due to incompatible water types and conflicting pH requirements and 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
Behaviour & Temperament
Both Amazon Leaf Fish and Violet Goby (Dragon Goby) are peaceful species with an aggression score of 2/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
In terms of spatial distribution, Amazon Leaf Fish prefers the Middle (Open Water) and Top (Surface) zones, whereas Violet Goby (Dragon Goby) occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Worth noting: Amazon Leaf Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
Water Parameters
The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
The pH requirements of Amazon Leaf Fish (5–6.8) and Violet Goby (Dragon Goby) (7.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Amazon Leaf Fish needs 0–8 dGH while Violet Goby (Dragon Goby) requires 12–25 dGH.
Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.
Tank Setup
To house Amazon Leaf Fish and Violet Goby (Dragon Goby) together, plan for an aquarium of at least 240 litres with a minimum length of 120 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: Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating, Sand (Sifters), Shells (Breeding/Hiding). 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.
Frequently Asked Questions
Can Amazon Leaf Fish and Violet Goby (Dragon Goby) live together?▾
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do Amazon Leaf Fish and Violet Goby (Dragon Goby) need?▾
A minimum of 240 litres (tank length at least 120 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 Amazon Leaf Fish and Violet Goby (Dragon Goby) together?▾
Keep the aquarium between 23°C and 28°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Amazon Leaf Fish or Violet Goby (Dragon Goby) aggressive?▾
Amazon Leaf Fish is peaceful (2/10) and Violet Goby (Dragon Goby) is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Amazon Leaf Fish and Violet Goby (Dragon Goby) need?▾
Their pH requirements do not overlap. Amazon Leaf Fish prefers 5–6.8, while Violet Goby (Dragon Goby) needs 7.5–8.5. This makes them incompatible in the same water chemistry.
Does Amazon Leaf Fish being nocturnal affect compatibility?▾
Amazon Leaf Fish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Amazon Leaf Fish during evening hours.
