Can Mbu Puffer and Yoyo Loach Live Together?
Keeping Mbu Puffer and Yoyo Loach together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 1800 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Mbu Puffer is a semi-aggressive species (7/10), while Yoyo Loach is generally mild-mannered (4/10). This modest difference means Mbu Puffer may occasionally assert dominance over Yoyo Loach.
Mbu Puffer and Yoyo Loach both frequent the Middle (Open Water) and 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: Yoyo Loach is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
To improve the chances of a peaceful coexistence in this community tank: Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
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 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 10–12 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Mbu Puffer and Yoyo Loach together, plan for an aquarium of at least 1800 litres with a minimum length of 240 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. 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 Mbu Puffer and Yoyo Loach live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 1800 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Mbu Puffer and Yoyo Loach need?▾
A minimum of 1800 litres (tank length at least 240 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 Mbu Puffer and Yoyo Loach 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 Mbu Puffer or Yoyo Loach aggressive?▾
Mbu Puffer is semi-aggressive (7/10) and Yoyo Loach is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Mbu Puffer and Yoyo Loach need?▾
Both species overlap in the 7–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Mbu Puffer nip Yoyo Loach's fins?▾
Mbu Puffer is a known fin nipper. If Yoyo Loach has long or flowing fins, there is a real risk of fin damage. Keeping Mbu Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
Does Yoyo Loach being nocturnal affect compatibility?▾
Yoyo Loach 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 Yoyo Loach during evening hours.
