Cat-eLog Data Sheet
Scientific Name	**Corydoras (lineage 8 sub-clade 4) arcuatus** Elwin, 1938
Common Names	CW036, Super Arcuatus Cory Bågpansarmal (Sweden), Buepansermalle (Denmark)
Type Locality	Amazon River (aquarium specimen).
Pronunciation	kor ee doh rass (lineage eight subclade four).
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. This specific epithet refers to its bowed (arcuatus=bowed, as in bent like an archer's bow) colour pattern.

Species Information
Size	60mm or 2.4" SL. Find near, nearer or same sized spp.
Identification	The colour pattern forms an even arch (hence the scientific name) of dark stripe from the snout to the lower back. Sometimes the cleithrum will have an iridescent gold or bronze color. Corydoras arcuatus is very similar to Corydoras granti. C. arcuatus can be distinguished by having a longer, straight snout, whereas C. granti has a shorter, more rounded snout. Also, the posterior margin of the pectoral fin spine of C. arcuatus has serrations pointing toward the origin of the spine (toward the body), whereas these serrations point toward the spine tip on C. granti. Finally, when full grown, C. arcuatus is a larger species than C. granti.
General Remarks	Corydoras arcuatus is very similar to C. granti , and specimens of C. granti are often sold by pet stores under the name C. arcuatus. A key to the arc-striped corys can be found in the forum HERE.
