Can Flagtail Prochilodus and Milomo Hap (Super VC10) Live Together?
Flagtail Prochilodus and Milomo Hap (Super VC10) are not recommended as tank mates due to 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
Can your tank handle Flagtail Prochilodus and Milomo Hap (Super VC10)?
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
Both Flagtail Prochilodus and Milomo Hap (Super VC10) are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Flagtail Prochilodus and Milomo Hap (Super VC10) 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: Flagtail Prochilodus 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.
The pH requirements of Flagtail Prochilodus (5.5–7.5) and Milomo Hap (Super VC10) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Flagtail Prochilodus and Milomo Hap (Super VC10) together, plan for an aquarium of at least 500 litres with a minimum length of 150 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: Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Sand (Sifters). 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.
Why This Pairing Usually Fails in Practice
Flagtail Prochilodus and Milomo Hap (Super VC10) 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Flagtail Prochilodus and Milomo Hap (Super VC10).
Frequently Asked Questions
Can Flagtail Prochilodus and Milomo Hap (Super VC10) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Flagtail Prochilodus and Milomo Hap (Super VC10) need?
A minimum of 500 litres (tank length at least 150 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 Flagtail Prochilodus and Milomo Hap (Super VC10) 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 Flagtail Prochilodus or Milomo Hap (Super VC10) aggressive?
Flagtail Prochilodus is moderately assertive (6/10) and Milomo Hap (Super VC10) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Flagtail Prochilodus and Milomo Hap (Super VC10) need?
Their pH requirements do not overlap. Flagtail Prochilodus prefers 5.5–7.5, while Milomo Hap (Super VC10) needs 7.8–8.6. This makes them incompatible in the same water chemistry.
How do I manage Milomo Hap (Super VC10)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Milomo Hap (Super VC10) 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.
