Schistura corica is a loach which prefers to be a lone specimen. These loaches are very territorial with each other! With other S. corica around in a small aquarium the result will be damaged fins and in some cases actually death with the constant harassment from the dominant loach. If keeping a group, then it's highly recommended that the aquarium is large enough to house individual territories for each occupant. Cover should be provided in different areas so that each loach can claim a territory of its own.
