I recently welcomed a Golden Oto Otocinclus Affinis into my 20-gallon freshwater aquarium, and I couldn’t be happier with my decision! These little guys are such diligent algae eaters, and within just a week, I noticed a significant improvement in my tank’s overall cleanliness. My aquarium plants, which were getting overwhelmed with algae, are now thriving thanks to these efficient little helpers. Compared to other algae eaters like the Flying Fox, the Golden Oto is much more peaceful and they don’t disturb my plants while munching away.
I appreciate their small size; they fit perfectly in my community tank without being aggressive. One minor concern is that they do prefer to be in groups of at least three, so I recommend considering that when adding them to your tank. Fortunately, they are easy to find and I ordered mine online with quick shipping. If you’re looking for a friendly, effective algae eater that will coexist well with other freshwater fish, I highly recommend the Golden Oto. They bring so much joy and help keep my aquarium healthy and beautiful!
