I recently added the Olga Cory – Corydoras Simulatus to my aquarium, and I couldn’t be happier! These Masquerade Corydoras are not only stunning with their unique patterns, but they’re also incredibly friendly. After about two weeks in my tank, they’ve settled in beautifully, swimming around playfully and foraging for food. I love how they scavenge the substrate together, which keeps my aquarium lively.
I’ve kept several types of catfish, but I find these corydoras to have such a charming personality compared to others. They tend to be more social and less skittish than some of my previous choices. Shipping was quick, and they arrived in perfect condition, which is so important for their welfare. Just a heads up, they do prefer to be in groups, so I recommend getting at least a few to really see their natural behavior shine.
If you’re looking for a peaceful and engaging addition to your aquarium fish collection, I wholeheartedly recommend these Corydoras. They’ve brought so much joy to my tank!

I recently added the Olga Cory – Corydoras Simulatus to my aquarium, and I couldn’t be happier! These little catfish have brought such vibrant life to my tank. After just two weeks, I noticed them darting around playfully and exploring every nook and cranny. Their peaceful nature makes them the perfect companions for my other community fish, and I love watching them interact.
What I appreciate most is how easy they are to care for. They thrive in a well-planted tank with gentle filtration, which I set up based on the helpful care instructions included with my order. I also love how their beautiful patterns add a unique aesthetic to my setup, way more engaging than other corydoras I’ve kept in the past.
One minor concern was that they were a bit shy at first, often hiding during the day, but now they’re much more active, especially during feeding time. If you’re looking for a peaceful and charming addition to your aquarium, I highly recommend the Olga Cory. They’re perfect for both beginners and seasoned aquarists alike. I will definitely be purchasing more in the future!
