A finnage mutation extending the dorsal, caudal and pectoral fins into flowing veils; often crossed onto albino or brown stock. Visually striking but the trailing fins are fragile.
Keeper tips for this variant
Avoid sharp decor and strong outflow nozzles, and keep nitrates low; ragged long fins are an early sign of poor water or fin-nipping tankmates.
