Can Walking Catfish (Clarias) and White Cheeked Goby Live Together?
Walking Catfish (Clarias) and White Cheeked Goby are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. 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 Walking Catfish (Clarias) and White Cheeked Goby?
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
Walking Catfish (Clarias) is a semi-aggressive species (8/10), while White Cheeked Goby is generally mild-mannered (4/10). This notable difference means Walking Catfish (Clarias) may occasionally assert dominance over White Cheeked Goby.
Walking Catfish (Clarias) and White Cheeked 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.
There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Worth noting: Walking Catfish (Clarias) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Walking Catfish (Clarias) is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 20°C and 24°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Walking Catfish (Clarias) and White Cheeked 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). Meeting these requirements will help both species thrive.
Walking Catfish (Clarias) prefers Low (Still Water) flow while White Cheeked Goby needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
Why This Pairing Usually Fails in Practice
Walking Catfish (Clarias) and White Cheeked Goby 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 Walking Catfish (Clarias) and White Cheeked Goby live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Walking Catfish (Clarias) and White Cheeked 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 Walking Catfish (Clarias) and White Cheeked Goby together?
Keep the aquarium between 20°C and 24°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.
Are Walking Catfish (Clarias) or White Cheeked Goby aggressive?
Walking Catfish (Clarias) is semi-aggressive (8/10) and White Cheeked Goby is generally mild-mannered (4/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Walking Catfish (Clarias) and White Cheeked Goby need?
Both species overlap in the 6.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage White Cheeked Goby's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives White Cheeked Goby 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.
Does Walking Catfish (Clarias) being nocturnal affect compatibility?
Walking Catfish (Clarias) 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 Walking Catfish (Clarias) during evening hours.
