Cory CW-045

The CW-045 cory is sometimes called the False Armatus Cory since it has a similar appearance to the armatus cory of Peru. However, these are different species and are caught in a difficult area to get to near the Colombia–Brazil border. To distinguish rarer cory, the trade began using CW numbers similar to the L numbers for plecos. This rare cory is generally just called the CW-045 cory. Both the CW and L numbers are not part of zoology. CW is a fiction like the L numbers for plecos; both were invented by the hobby community and are not a true part of zoology. DATZ, a German magazine, came up with the L numbers for plecos so we can figure out who is who. The hobby site CorydorasWorld invented the CW system for corys. It works, because no one else has come up with a more common name for Cory CW-045, and we all know what cory it is.

Cory CW-045 is a big cory, getting to three inches, and is charcoal with a red sash on the head.

Quick Facts

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: Corys sift through the substrate with their sensitive barbels, so soft sand or smooth, fine gravel keeps those barbels healthy.
