Can Amazon Puffer and Violet Goby (Dragon Goby) Live Together?
Amazon Puffer and Violet Goby (Dragon Goby) are not recommended as tank mates due to incompatible water types. 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
Amazon Puffer is a generally mild-mannered species (3/10), while Violet Goby (Dragon Goby) is peaceful (2/10). This modest difference means Amazon Puffer may occasionally assert dominance over Violet Goby (Dragon Goby).
Amazon Puffer and Violet Goby (Dragon Goby) 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Worth noting: Amazon Puffer is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Amazon Puffer is a known jumper, so a tight-fitting lid is essential.
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.
Both fish can tolerate a pH between 7.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 12–15 dGH. Regular testing will ensure conditions stay within this range.
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 Puffer 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: Sand (Sifters), Driftwood (Digestion/Hiding), Plants - Densely covered, Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
Frequently Asked Questions
Can Amazon Puffer 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 Puffer 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 Puffer 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 Puffer or Violet Goby (Dragon Goby) aggressive?▾
Amazon Puffer is generally mild-mannered (3/10) and Violet Goby (Dragon Goby) is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Amazon Puffer and Violet Goby (Dragon Goby) need?▾
Both species overlap in the 7.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Amazon Puffer nip Violet Goby (Dragon Goby)'s fins?▾
Amazon Puffer is a known fin nipper. If Violet Goby (Dragon Goby) has long or flowing fins, there is a real risk of fin damage. Keeping Amazon Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
Does Amazon Puffer being nocturnal affect compatibility?▾
Amazon Puffer 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 Puffer during evening hours.
