First Fish! - Corydoras Melanistius

First life into the Aquarium 3 Corydoras Melanistius

The bluespotted corydoras, blacksail corydoras, blackspotted corydoras, dotted corydoras, Guiana cat or Guiana corydoras (Corydoras melanistius) is a tropical freshwater fish belonging to the Corydoradinae sub-family of the Callichthyidae family. It originates in inland waters in South America, and is found in the coastal rivers of French Guiana, Guyana, and Suriname. The specific epithet melanistius means black sail, referring to the dorsal fin.

I picked them up from the local fish store on my way home they were around $6 ea. Hoping the larger one is a female but I really have no experience sexing corys. So far they've just been on shrimp pellets but once I add the guppies they will start to receive some variables in their diet.
