Care notes
Small algae-eating catfish. Schooling; keep 6+. Sensitive to water quality and shipping stress. Needs established tank with biofilm/algae. Soft substrate preferred.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
