Aequidens Diadema

• Temperament: Generally calm but territorial and assertive, especially when breeding.

• Tank Size: A minimum of 30-40 gallons is recommended for a pair, though larger is better to accommodate their 6-7 inch adult size.

• Diet: Omnivorous; they readily accept high-quality flakes, granules, pellets, and frozen foods like bloodworms and brine shrimp.

• Water Parameters: They prefer slightly acidic to neutral, soft to moderately hard water typical of slow-moving South American rivers.

• Breeding: They are, or act as, delayed mouthbrooders.

Appearance and Behavior

• Colors: Silver-gray base with a prominent black lateral spot, blue-green iridescent face markings, and hints of orange or yellow on the fins.

• Compatibility: Suitable for larger, mature community aquariums with tankmates such as larger tetras, barbs, rainbowfish, or other moderate cichlids.

• Environment: Appreciate a tank with plenty of swimming space, caves, and places to hide among driftwood or rocks.

They are sometimes confused with or sold under the name Bujurqi or Pendex cichlid.
