At a Glance
Behaviour & Temperament
Amazon Leaf Fish is a peaceful species (2/10), while Indonesian Datnoid (Tiger Fish) is moderately assertive (6/10). This notable difference means Indonesian Datnoid (Tiger Fish) may occasionally assert dominance over Amazon Leaf Fish.
Amazon Leaf Fish and Indonesian Datnoid (Tiger Fish) 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: Amazon Leaf Fish 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 6.5 and 6.8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amazon Leaf Fish and Indonesian Datnoid (Tiger Fish) together, plan for an aquarium of at least 816 litres with a minimum length of 180 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: Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating. Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
