I am completely smitten with my new Sterbai Corydoras! After about two months of having them in my 55-gallon community tank, I’ve seen such a positive change in the overall environment. These little guys are not just charming to watch as they scuttle around the substrate, but their presence has encouraged a healthier ecosystem. They are fantastic scavengers and help keep the tank clean, which is a huge bonus for any aquarium owner.
I used to have another brand of corydoras, but my Sterbais are definitely more active and social, interacting with each other and my other fish more frequently. They’re gentle but quite playful, making them perfect for a community tank setup.
On top of that, they shipped quickly and arrived healthy and vibrant. I did notice that they took a little while to acclimate, which is normal, but within a week they were fully settled in and thriving.
If you’re an aquarium enthusiast looking to add some lively and adorable characters to your tank, I wholeheartedly recommend the Sterbai Corydoras. Just ensure you provide them with plenty of hiding places and soft substrate; they love to dig! Overall, they’ve been a delight and I would definitely purchase them again!

I’ve been keeping fish for over five years now, and I can confidently say that my Sterbai Corydoras are one of the best additions to my community tank! I purchased three of them about two months ago, and they have quickly become my favorites. Not only are these tropical fish incredibly active and playful, but they also help keep the substrate clean by scavenging for leftovers. Their adorable little faces and the way they swim in groups just bring so much joy to my aquarium! Compared to other catfish types I’ve had, like the Bristlenose, the Sterbai’s peaceful nature truly makes them better suited for a community setting. They coexist beautifully with my Tetras and Guppies. My only minor issue was that they took a few days to acclimate, but once settled, they thrived! I wholeheartedly recommend Sterbai Corys for both first-time aquarists and seasoned enthusiasts. They’re not just fish; they’re delightful little companions that enrich your aquarium experience!
