Scientific Name	**Corydoras (lineage 8 sub-clade 1) multiradiatus** (Orcés V., 1960)
Common Names	Hognose Brochis Brochis-Panzerwels (Germany), Long-finned Brochis, Spidsnæset Kæmpepansermalle (Denmark)
Type Locality	Tributary of Río Lagartococha near town of Garza-Cocha, upper Río Napo system, Province Napo, Ecuador.
Synonym(s)	Brochis multiradiatus, Chaenothorax multiradiatus
Pronunciation	kor ee doh rass (lineage eight subclade one). - MULL tee rad ee ATT uss
Etymology	Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. multi=many, radiatus= rays, in reference to the number of dorasl fin rays.

Species Information
Size	67mm or 2.6" SL. Find near, nearer or same sized spp.
Identification	Commonly referred to by the currently synonymised genus Brochis, this sub-clade can be distinguished from other corydoradine species by the fact that they have more than 10 rays in the dorsal fin, whilst all other members of the Corydoradinae have seven rays. Differs from other species of Brochis by its hog-like snout and from B. splendens by a larger number of dorsal fin rays. The dorsal fin can have 15-18 soft rays; although B. multiradiatus usually has 17.
Sexing	Undocumented, although it is presumed mature females are larger and fuller when carrying eggs.

Husbandry Information
Feeding	A fish that likes to dig around for food, but will eat all prepared foods that find their way to the substrate. Live bloodworms or tubifex are especially relished - be careful with the tubifex. It can be difficult to feed carefully and if it starts living in the tank water conditions can quickly deteriorate. This can, at least in part, be controlled by offering tubifex in a shallow ceramic bowl.
Furniture	Open spaces of substrate and rock or wood refuges slightly elevated to provide the shade these fish like to rest under in rare moments of inactivity. This species will gleefully uproot plants at the first opportunity, use plant pots or other methods of fixing plants in place.
Compatibility	An ideal community tank resident, keep in shoals.
Suggested Tankmates	Can be kept with most fish. More suitable for keeping with loaches than Corydoras as their larger size helps them compete better for food. Boisterous enough to be kept with more dynamic aquaria. Perfect for an Amazon river biotope.
Breeding	Reported by no details survive of the account save it is supposed to spawn in a manner similar to Corydoras.
Breeding Reports	There is no breeding report.
