Behaviour & Temperament

Amazon Leaf Fish is a peaceful species (2/10), while Jurupari Eartheater is generally mild-mannered (3/10). This modest difference means Jurupari Eartheater may occasionally assert dominance over Amazon Leaf Fish.

In terms of spatial distribution, Amazon Leaf Fish prefers the Middle (Open Water) and Top (Surface) zones, whereas Jurupari Eartheater occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Amazon Leaf Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

Water Parameters

The safe temperature window for both species falls between 26°C and 29°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

Both fish can tolerate a pH between 5.5 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 1–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Amazon Leaf Fish and Jurupari Eartheater together, plan for an aquarium of at least 280 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: Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Jurupari Eartheater is a plant destroyer, which conflicts with Amazon Leaf Fish's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Amazon Leaf Fish and Jurupari Eartheater need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

What size tank do Amazon Leaf Fish and Jurupari Eartheater need?

A minimum of 280 litres (tank length at least 120 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 Amazon Leaf Fish and Jurupari Eartheater together?

Keep the aquarium between 26°C and 29°C. A target of around 27.5°C sits comfortably within both species' preferred ranges.

Are Amazon Leaf Fish or Jurupari Eartheater aggressive?

Amazon Leaf Fish is peaceful (2/10) and Jurupari Eartheater is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Amazon Leaf Fish and Jurupari Eartheater need?

Both species overlap in the 5.5–6.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

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.
