Behaviour & Temperament

Loxozonus Corydoras (C079/C082) is a peaceful species (0/10), while Pearl Eartheater is moderately assertive (6/10). This notable difference means Pearl Eartheater may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

Large aggression gap (6 points) between Loxozonus Corydoras (C079/C082) and Pearl Eartheater increases stress risk for the more peaceful fish.

Loxozonus Corydoras (C079/C082) and Pearl Eartheater 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Loxozonus Corydoras (C079/C082) and Pearl Eartheater to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Loxozonus Corydoras (C079/C082) and Pearl Eartheater together, plan for an aquarium of at least 250 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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.

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. Loxozonus Corydoras (C079/C082) and Pearl 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 Loxozonus Corydoras (C079/C082) and Pearl Eartheater need?

A minimum of 250 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 Loxozonus Corydoras (C079/C082) and Pearl Eartheater together?

Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Loxozonus Corydoras (C079/C082) or Pearl Eartheater aggressive?

Loxozonus Corydoras (C079/C082) is peaceful (0/10) and Pearl Eartheater is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Loxozonus Corydoras (C079/C082) and Pearl Eartheater need?

Both species overlap in the 6–7.2 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Pearl Eartheater's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Pearl Eartheater space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
