Otos feel better, and do better, in larger groups (like 6 or more).. that said with that tank size.. it depends on your filtration and water changes. I'd personally try to do what it took to maintain 6 otos.. for their own sake. You will also see them more then.
20g long with Otos, Corydoras Pygmaeus, RCS and Nerites
2.6 gal nano planted Sparkling gourami breeding tank
2 gal planted Betta Splendens tank
