My Otocinclus has been thriving in a 30-gallon tank for over a year. It’s very peaceful and always active on the glass, feeding on algae. I feed it algae wafers daily and it seems to enjoy it. Easy to care for and a great addition to a community tank.

The fish arrived healthy and has adapted well to my tank. I keep the water parameters stable and feed it algae daily. It’s not very active, but it’s calm and doesn’t bother other fish. A good choice for beginners.
