Can Amazon Leaf Fish and Black Skirt Tetra Live Together?
Keeping Amazon Leaf Fish and Black Skirt Tetra together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 90 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Amazon Leaf Fish is a peaceful species (2/10), while Black Skirt Tetra is generally mild-mannered (4/10). This modest difference means Black Skirt Tetra may occasionally assert dominance over Amazon Leaf Fish.
Amazon Leaf Fish and Black Skirt Tetra 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.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
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. 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 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 6 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 3–8 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amazon Leaf Fish and Black Skirt Tetra together, plan for an aquarium of at least 90 litres with a minimum length of 60 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.
Frequently Asked Questions
Can Amazon Leaf Fish and Black Skirt Tetra live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 90 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Amazon Leaf Fish and Black Skirt Tetra need?▾

What water temperature is best for Amazon Leaf Fish and Black Skirt Tetra together?▾
Keep the aquarium between 23°C and 26°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are Amazon Leaf Fish or Black Skirt Tetra aggressive?▾
Amazon Leaf Fish is peaceful (2/10) and Black Skirt Tetra is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Amazon Leaf Fish and Black Skirt Tetra need?▾
Both species overlap in the 6–6.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Black Skirt Tetra nip Amazon Leaf Fish's fins?▾
Black Skirt Tetra is a known fin nipper. If Amazon Leaf Fish has long or flowing fins, there is a real risk of fin damage. Keeping Black Skirt Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
Does Amazon Leaf Fish being nocturnal affect compatibility?▾
Amazon Leaf Fish 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 Amazon Leaf Fish during evening hours.
