Behaviour & Temperament
Motoro Stingray is a moderately assertive species (5/10), while Violet Goby (Dragon Goby) is peaceful (2/10). This modest difference means Motoro Stingray may occasionally assert dominance over Violet Goby (Dragon Goby).
Motoro Stingray 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.
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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°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.
Hardness requirements are incompatible: Motoro Stingray needs 2–10 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 Motoro Stingray and Violet Goby (Dragon Goby) together, plan for an aquarium of at least 750 litres with a minimum length of 180 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), Smooth Gravel (Sensitive Barbels), Shells (Breeding/Hiding), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Motoro Stingray 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 Motoro Stingray and Violet Goby (Dragon Goby) need?
A minimum of 750 litres (tank length at least 180 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 Motoro Stingray and Violet Goby (Dragon Goby) together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Motoro Stingray or Violet Goby (Dragon Goby) aggressive?
Motoro Stingray is moderately assertive (5/10) and Violet Goby (Dragon Goby) is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Motoro Stingray 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.
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.
