It's all about the oto!

Welcome to otocinclus.com, a website dedicated to the Otocinclus catfish. It contains articles on the care of Otocinclus, breeding tips, and anything else I can find about this awesome fish! It will also hold various articles on the general care of freshwater aquarium fish (aimed toward beginners).

This site is mainly for novice fishkeepers who want to learn more about otocinclus catfish, but it is also for those advanced fishkeepers who can't seem to keep these fish alive and need a few pointers. Not overly technical or scientific, I hope you enjoy this site and check back often as new things are added frequently.
