Filtration & Aeration

A reliable filter helps keep the water clean and well-oxygenated. Paradise fish thrive in well-filtered tanks, but avoid strong currents—they prefer gentle flow.

Substrate & Decor

Compatibility & Behavior

• Community tanks: Paradise fish can coexist peacefully with other non-aggressive or similarly sized fish
• Tank mates: Suitable companions include peaceful tetras, rasboras, and danios
• Territoriality: Males can be aggressive, especially during breeding season
• Breeding: Males build bubble nests; separate females afterward to prevent injury

Maintenance & Care

• Perform regular water changes (25-30% weekly)
• Monitor water parameters routinely
• Keep an eye out for signs of stress or illness, such as faded colors or lethargy
• Quarantine new fish before adding them to the main tank

Common Diseases & Prevention

• Ich (White Spot Disease): Look for white spots; treat with medication

Maintaining clean water and a stress-free environment are vital in preventing diseases.
