They really do best in groups and in planted tanks because they're pretty sensitive to parameter changes.
Oh wow, yea you're already really overstocked because mollies need at least a 20-30 gallon.
If you can rehome the mollies you could get another Oto, and maybe some nano fish like green neon tetras, ember tetras, or a beta.
Sorry to disagree here, but with all the debate about tank sizes and overstocking on this and other forums, why would you consider green neons or ember tetras as nano fish?
Tetras are extremely active fish with generally high oxygen requirements and low tolerence to poor water quality. Green neons, in my experience, are especially sensitive. Any changes in water quality in a small environment are usually quick and often devastating to such sensitive fish.
that's awesome! My new otos hang with my habrosus to! They're becoming fast friends...If it's a new 5g the Oto may starve from lack of biofilm and algae. Try putting some smooth aquarium safe river rocks in a shallow dish of water in a sunny window to grow him some food. Rehome the Mollies ASAP. IMHO Return or rehome the Oto to a bigger tank with other Otos. Mine loved sitting on my plants and hanging out with my other Catfish. This is one of my 10g tanks There are 2 species of Oto in the pic. I had 3 different species at one point. Here is a link to the known species of Otocinclus http://www.planetcatfish.com/common/genus.php?genus_id=49 Smoke signals from my iPhone using Tapatalk
