Can Panda Corydoras and Violet Goby (Dragon Goby) Live Together?
Panda Corydoras and Violet Goby (Dragon Goby) are not recommended as tank mates due to incompatible water types and conflicting pH requirements. 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
Panda Corydoras is a peaceful species (0/10), while Violet Goby (Dragon Goby) is peaceful (2/10). This modest difference means Violet Goby (Dragon Goby) may occasionally assert dominance over Panda Corydoras.
Panda Corydoras 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: Violet Goby (Dragon Goby) 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 25°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.
The pH requirements of Panda Corydoras (6–7.4) and Violet Goby (Dragon Goby) (7.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 12–12 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. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Panda Corydoras 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), Shells (Breeding/Hiding), Driftwood (Digestion/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 Panda Corydoras 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 Panda Corydoras 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 Panda Corydoras and Violet Goby (Dragon Goby) together?▾
Keep the aquarium between 23°C and 25°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.
Are Panda Corydoras or Violet Goby (Dragon Goby) aggressive?▾
Panda Corydoras is peaceful (0/10) and Violet Goby (Dragon Goby) is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Panda Corydoras and Violet Goby (Dragon Goby) need?▾
Their pH requirements do not overlap. Panda Corydoras prefers 6–7.4, while Violet Goby (Dragon Goby) needs 7.5–8.5. This makes them incompatible in the same water chemistry.
Does Violet Goby (Dragon Goby) being nocturnal affect compatibility?▾
Violet Goby (Dragon Goby) 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 Violet Goby (Dragon Goby) during evening hours.
