Behaviour & Temperament

Blue Botia is a moderately assertive species (6/10), while Dojo Loach (Weather Loach) is peaceful (2/10). This notable difference means Blue Botia may occasionally assert dominance over Dojo Loach (Weather Loach).

Blue Botia and Dojo Loach (Weather Loach) 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.

Worth noting: Blue Botia is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Dojo Loach (Weather Loach) is a known jumper, so a tight-fitting lid is essential.

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. 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 23°C and 24°C. Aim for the midpoint of this range (around 23.5°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Blue Botia and Dojo Loach (Weather Loach) together, plan for an aquarium of at least 283 litres with a minimum length of 120 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), 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.

What water temperature is best for Blue Botia and Dojo Loach (Weather Loach) together?

Keep the aquarium between 23°C and 24°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.

Are Blue Botia or Dojo Loach (Weather Loach) aggressive?

Blue Botia is moderately assertive (6/10) and Dojo Loach (Weather Loach) is peaceful (2/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Blue Botia and Dojo Loach (Weather Loach) need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Blue Botia nip Dojo Loach (Weather Loach)'s fins?

Blue Botia is a known fin nipper. If Dojo Loach (Weather Loach) has long or flowing fins, there is a real risk of fin damage. Keeping Blue Botia in a larger group can help redirect nipping behaviour toward conspecifics.

Does Blue Botia being nocturnal affect compatibility?

Blue Botia 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 Blue Botia during evening hours.
