Cleidopus Gloriamaris (The Pineapplefish)

Overview

• Native to the coastal waters of Australia, particularly found in deep rocky reefs and caves.
• Recognized by its armored, yellow body covered in black-edged scales resembling a pineapple.
• Known for its bioluminescent organs located near its lower jaw, which it uses to attract prey.
• A nocturnal species that remains hidden in caves and crevices during the day, becoming active at night.
• Best suited for large aquariums with subdued lighting, stable water parameters, and ample hiding spots.

Feeding

• Carnivorous, primarily preying on small crustaceans and zooplankton in its natural habitat.
• Requires a diet of live or frozen mysis shrimp, brine shrimp, and finely chopped seafood.
• May take time to adjust to prepared foods but can eventually accept high-quality marine pellets.
• Should be fed in low-light conditions to mimic its natural nocturnal hunting behavior.
• A diet rich in protein supports its slow metabolism and overall health.

Habitat

• Prefers deep reef environments, caves, and rocky crevices with minimal light exposure.
• Frequently found resting in shaded areas, using its armored scales as protection from predators.
• Aquarium setups should include plenty of live rock, creating cave-like structures for shelter.
• Requires high-quality filtration and stable water conditions to thrive.
• Providing a dimly lit environment helps reduce stress and encourages natural behaviors.

Fish Care

• Optimal water temperature: 72-78°F (22-26°C) to maintain stability.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires slow-moving water flow to replicate its deep reef habitat.
• Not considered reef-safe, as it may consume small crustaceans and other invertebrates.
• Providing an environment with low lighting and ample caves supports its nocturnal nature.

Compatibility

• Generally peaceful but may prey on smaller fish and shrimp.
• Compatible with other nocturnal or slow-moving species that will not outcompete it for food.
• Should not be housed with highly aggressive fish that may stress or harass it.
• Best suited for a species-only tank or a carefully selected community of non-aggressive tankmates.
• Providing multiple hiding spots minimizes stress and promotes natural behavior.

Aquarium Behavior

• A slow-moving species that spends much of its time resting in crevices.
• Becomes more active at night, using its bioluminescent organs to attract small prey.
• Rarely engages in aggressive behavior but may eat smaller tankmates if given the opportunity.
• Providing a dimly lit environment with plenty of hiding spaces enhances its natural behaviors.
• Over time, it may become accustomed to its caretaker and recognize feeding routines.
