I’ve been keeping fish for over 5 years, but my recent addition of the Little Cory Corydoras Nanus has been such a delight! These tiny catfish are not just adorable with their light spots, but they are also incredibly hardy and sociable. I introduced a group of 6 into my 20-gallon tank about 2 months ago, and they quickly formed a lovely shoal, scuttling around the substrate in search of food. Watching them interact brings so much joy! They are great at keeping the bottom of the tank clean, too. Compared to other catfish I’ve had, these little guys are much more active and engaging, often playing amongst themselves rather than hiding. My only minor concern is that they do prefer a slightly sandy substrate, as they can be sensitive to sharp edges. But overall, they are perfect for community tanks and will thrive alongside peaceful species. If you’re looking to add some personality to your aquarium, I can’t recommend these little catfish enough. They truly have a vibrant presence and contribute positively to my underwater ecosystem!
