Behaviour & Temperament

Forktail Blue-eye is a peaceful species (2/10), while Yoyo Loach is generally mild-mannered (4/10). This modest difference means Yoyo Loach may occasionally assert dominance over Forktail Blue-eye.

Forktail Blue-eye and Yoyo Loach both frequent the Middle (Open Water) 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. Also, Forktail Blue-eye is a known jumper, so a tight-fitting lid is essential.

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 5–12 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Forktail Blue-eye and Yoyo Loach together, plan for an aquarium of at least 132 litres with a minimum length of 90 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: Plants - Densely covered, Sand (Sifters), Smooth Gravel (Sensitive Barbels), 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 Forktail Blue-eye and Yoyo Loach live together?

Yes. Forktail Blue-eye and Yoyo Loach are considered ideal tank mates. Their water parameters, temperaments, and behaviour profiles are well matched for a community aquarium.

What size tank do Forktail Blue-eye and Yoyo Loach need?

A minimum of 132 litres (tank length at least 90 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 Forktail Blue-eye 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 Forktail Blue-eye or Yoyo Loach aggressive?

Forktail Blue-eye is peaceful (2/10) and Yoyo Loach is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Forktail Blue-eye 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 Yoyo Loach nip Forktail Blue-eye's fins?

Yoyo Loach is a known fin nipper. If Forktail Blue-eye has long or flowing fins, there is a real risk of fin damage. Keeping Yoyo Loach 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.
