I recently added the 6 Penguin Tetras to my 40-gallon freshwater tank, and I couldn’t be happier! These little guys have been swimming gracefully for about two months now, and their striking colors truly enhance the overall aesthetic of my aquarium. Compared to other fish I’ve kept, the Penguin Tetras are incredibly social and seem to thrive in a community setting. I’ve noticed their vibrant hues become even more pronounced under good lighting, adding a beautiful visual contrast alongside my neon tetras.
While I initially worried about compatibility, they’ve integrated seamlessly with my other fish, showing no signs of aggression. They spend their days darting around and exploring every nook of the tank, which brings me so much joy. It’s heartwarming to see them so happy and healthy!
The only minor concern was their initial shyness; it took about a week for them to come out of their shells, but now they are the stars of the show! I highly recommend these tetras to anyone looking to add a lively and beautiful freshwater fish. They’d be perfect for both beginners and seasoned hobbyists who want to enhance their South American fish collection.
