The long fin green cory is a bred variation of the wild emerald green cory. These aquarium catfish only grow to half the size of the wild Brochis splendens, but they feature a long dorsal fin (sailfin). Like all cory, the long fin cory is hardy, a great scavenger, and prefers to run around in packs.

Care Guide
Tank setup: Give them a heater, a gentle filter and a soft sand or smooth, fine gravel bottom. Plants, driftwood and a few shady spots help them feel secure. Corys are sensitive to salt and some medications (especially copper), so check labels before treating the tank.
Feeding: Corys need their own food, not just leftovers. Feed sinking pellets or wafers once or twice a day so food reaches the bottom. They also enjoy frozen foods like bloodworms and brine shrimp.
Tankmates: Corys get along with almost any peaceful community fish, such as tetras, rasboras, livebearers, gouramis, angelfish and bettas. Avoid large fish that could swallow them and aggressive bottom dwellers.
Good to know: The tall sailfin is a target for fin-nippers, so keep them with gentle tankmates.
