Care Guide

Diet

The Crested Puffer is a strict carnivore that thrives on a varied diet of live and frozen foods such as snails, bloodworms, brine shrimp, and small crustaceans. Snails are especially important as they help wear down the puffer's ever-growing beak. Feed adults once or twice daily, offering only what they can consume in a few minutes to maintain water quality.

Behavior

Crested Puffers are bold, curious, and highly intelligent fish that will often interact with their owners. Males are particularly territorial and aggressive, especially toward conspecifics and similarly shaped fish. They are active swimmers that explore all levels of the tank and may nip at the fins of tankmates.

Breeding

Breeding Crested Puffers in captivity is rare and considered difficult. Males will court females with displays of their crest and coloration, and eggs are typically scattered among fine-leaved plants. Raising fry is challenging as they require infusoria and very small live foods in the early stages.

Common Diseases

Ich (White Spot Disease)

Symptoms

Small white spots resembling grains of salt on the body and fins, flashing, lethargy

Treatment

Raise water temperature gradually to 28-30°C and treat with ich-specific medication; puffers are scaleless and sensitive to medications, so use half doses with caution.

Overgrown Beak

Symptoms

Difficulty eating, visible overgrowth of the beak/teeth, weight loss

Treatment

Provide hard-shelled foods like snails regularly to naturally wear down the beak; manual trimming by an experienced aquarist or vet may be required in severe cases.

Internal Parasites

Symptoms

Bloating, white or stringy feces, loss of appetite, weight loss despite eating

Treatment

Treat with antiparasitic medications such as metronidazole or praziquantel added to food or water; quarantine affected fish.

Bacterial Infection

Symptoms

Redness, ulcers, fin rot, lethargy, loss of appetite

Treatment

Improve water quality immediately and treat with broad-spectrum antibiotics such as kanamycin or erythromycin; avoid salt treatments as puffers are sensitive.
