Relevant Information:

Very similar to C. garbei which was the fish that hobbyists thought that this Cory was in the 1980s and 90s. Dorsal spines (total): 1; Dorsal soft rays (total): 6 - 8; Anal spines: 0; Anal soft rays: 8 - 10. Differentiated in having serrations of posterior borders of pectoral spine restricted to proximal half of spine, and parapophyses of fourth free vertebra reduced, separated from each other, and not fused into haemal arch. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and good quality flake to name but a few.

Common Name:
