The Hognose brochis, or more elegantly named cory multiradiatus, is the largest of the aquarium cory and is caught in the wilds of Ecuador. Hognose brochis look like giant emerald green cory and are about three inches in size. Despite the size, these are gentle giants and scavenge and root around just like little corydoras.
The name multiradiatus comes from the 18 rays on the wide dorsal fin.

Care Guide
Tank setup: These larger corys need a wide, open sandy bottom, a heater, good filtration and some plants or driftwood for cover. 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: They get along with most peaceful community fish, including larger tetras, gouramis, angelfish and other corys. Avoid fish big enough to swallow them.
Good to know: Hognose brochis are the largest corys. They need bigger sinking foods than small corys, but are just as peaceful.
