Behaviour & Temperament

Aequidens diadema (Diadem Cichlid) is a moderately assertive species (6/10), while Jurupari Eartheater is generally mild-mannered (3/10). This modest difference means Aequidens diadema (Diadem Cichlid) may occasionally assert dominance over Jurupari Eartheater.

Aequidens diadema (Diadem Cichlid) and Jurupari 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 Aequidens diadema (Diadem Cichlid) and Jurupari Eartheater to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

Water Parameters

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

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Aequidens diadema (Diadem Cichlid) and Jurupari Eartheater together, plan for an aquarium of at least 361 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 β€” caves, driftwood, and dense plant clusters β€” so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Aequidens diadema (Diadem Cichlid) and Jurupari Eartheater.
