Behaviour & Temperament

Banana Loach is a peaceful species (2/10), while Blue Dolphin (Hap) is moderately assertive (5/10). This modest difference means Blue Dolphin (Hap) may occasionally assert dominance over Banana Loach.

Banana Loach and Blue Dolphin (Hap) 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Banana 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: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

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 7.8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Banana Loach and Blue Dolphin (Hap) together, plan for an aquarium of at least 475 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.

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), Smooth Gravel (Sensitive Barbels). 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Banana Loach and Blue Dolphin (Hap).

Frequently Asked Questions

Can Banana Loach and Blue Dolphin (Hap) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 475 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Banana Loach and Blue Dolphin (Hap) need?

A minimum of 475 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 Banana Loach and Blue Dolphin (Hap) 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 Banana Loach or Blue Dolphin (Hap) aggressive?

Banana Loach is peaceful (2/10) and Blue Dolphin (Hap) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Banana Loach and Blue Dolphin (Hap) need?

Both species overlap in the 7.5–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Banana Loach being nocturnal affect compatibility?

Banana 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 Banana Loach during evening hours.
