Apogon parvulus 1.5-3 cm

Apogon parvulus – Bright Red Pygmy Cardinalfish

The Apogon parvulus is a miniature cardinalfish with a semi-transparent body, measuring barely 3 to 4 cm. Highly sought after for its bright color, it moves in tight schools within coral massifs, creating an exceptional visual effect in reef aquariums.

A Discreet Fish with a Nocturnal Lifestyle

Native to the Indo-Pacific region, this pygmy fish is active in the evening and at night. It particularly appreciates well-structured aquariums with shaded hiding spots such as rock crevices or branches of hard corals. During the day, it often remains discreet, but as soon as night falls, it forms a bright red cloud in the center of the setup.

Maintenance Conditions

• Minimum recommended volume: 80 liters (100 L+ for a group)
• Temperature: 24°C to 28°C
• pH: 8.0 to 8.4
• Decor: live rocks, branches, caves
• Water flow: low to moderate

Behavior and Compatibility

Very peaceful, the Apogon parvulus should be kept in groups of 5 to 10 individuals to encourage natural behaviors. It coexists perfectly with other small reef fish, invertebrates, and corals. It is recommended to avoid overly lively or aggressive companions.

Feeding

• Frozen or live plankton
• Nauplii, brine shrimp, mysis
• Very fine granules or specialized liquid food

With its flaming red coloration, small size, and fascinating gregarious behavior, Apogon parvulus is an ideal choice to add color and movement to a miniature reef. It will appeal to both beginners and demanding reef aquarium enthusiasts.
