Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Possible with Caution

Keeping Glass Catfish and Jurupari Eartheater together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 280 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Glass Catfish and Jurupari Eartheater?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Glass Catfish is a peaceful species (1/10), while Jurupari Eartheater is generally mild-mannered (3/10). This modest difference means Jurupari Eartheater may occasionally assert dominance over Glass Catfish.

In terms of spatial distribution, Glass Catfish prefers the Middle (Open Water) zone, 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.

Water Parameters

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 1–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Glass Catfish 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: Plants - Densely covered, Plants - Floating, Sand (Sifters), Driftwood (Digestion/Hiding), 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 Glass Catfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) 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. Glass Catfish 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 Glass Catfish 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 Glass Catfish and Jurupari Eartheater together?

Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are Glass Catfish or Jurupari Eartheater aggressive?

Glass Catfish is peaceful (1/10) and Jurupari Eartheater is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Glass Catfish and Jurupari Eartheater need?

Both species overlap in the 6–7 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
