Yes, like most fish, Otocinclus reproduce by laying eggs. However, breeding Otocinclus in home aquariums can be a challenging endeavor as it requires specific conditions. The water temperature, pH levels, and other water parameters need to be optimal for successful breeding.
The female lays eggs on the aquarium glass, plants, or other surfaces, and the male then fertilizes them. Once hatched, the fry can be tricky to care for due to their small size and specific food requirements. For hobbyists interested in breeding these creatures, adequate research and preparation is recommended.
