The Longfin Clownfish is a designer variant of the popular clownfish species, known for its extended, flowing fins and peaceful nature. It grows up to 3 inches and thrives in tanks of 20 gallons or more, making it suitable for both beginners and advanced aquarists. Hardy and reef-safe, it does well in community reef tanks and may host in anemones, though it's not required. Provide stable water parameters, moderate flow, and a balanced diet of meaty foods and high-quality pellets. Longfin varieties may be slightly less agile swimmers, so avoid strong currents and aggressive tankmates.
