Relevant Information:

Similar to C020 which has proven to be juvenile C. arcuatus. Corydoras arcuatus will actualy turn out to be CW036. Dorsal spines (total): 1; Dorsal soft rays (total): 8; Anal soft rays: 8. Distinguished from all its congeners except Corydoras arcuatus, Corydoras narcissus, and Corydoras gracilis, by having a long, arched, dark stripe, running parallel to the dorsal profile and extending at least from the anterior margin of the first dorsolateral body plate to the caudal peduncle. Can be diagnosed from Corydoras arcuatus, Corydoras gracilis, and Corydoras narcissus in having the arc-like stripe terminating posterior to the orbit (vs. extending onto snout). Further differs from Corydoras arcuatus by having fewer free vertebrae (21 vs. 27); lateral profile of the snout distinctly rounded (vs. nearly straight); a greater preadipose distance (84.0-86.7% SL, vs. 82.9-83.8% SL); and the posterior limit of the cleithrum at a vertical through the dorsal-fin spinelet (vs. between the third and fourth dorsal-fin rays); from Corydoras gracilis by having fewer free vertebrae (21 vs. 27); arched stripe extending posteriorly to the base of the lower caudal-fin rays (vs. reaching the base of the upper caudal-fin rays); and the second infraorbital contacting only the sphenotic (vs. contacting both the sphenotic and compound pterotic); from Corydoras narcissus in having the arched stripe extending posteriorly across the lower caudal-fin rays (vs. extending over the lower caudal-fin rays); lateral profile of the snout distinctly rounded (vs. nearly straight); and minute and weak pectoral-spine serrations (vs. large and strong serrations). Aquarium Care: A tank setup would entail a soft substrate such as sand or a small gravel and a nice plant covering around the back and sides of the aquarium. If housed in a community tank a mixture of small South American characins or the smaller varieties of Asian Rasboras would suffice, as larger fishes would intimidate these shy Cory's, and would stop them eating and would be therefore detrimental to their overall health. Diet: A good quality flake food and tablet food for adults with sparodic feedings of frozen or live food will keep your Corydoras in good health.
