I recently added the Coral Red Pencilfish (Nannostomus Mortenthaleri) to my aquarium, and I couldn’t be happier! These little beauties not only bring a splash of color but also a lively energy that makes the tank come alive. After about two weeks of observing them, it’s clear they thrive in a peaceful community setup. They get along wonderfully with my neon tetras, creating a harmonious environment.
What I love most is how they showcase their vibrant colors, especially when they swim in schools. I started with a group of six, and they seem much happier moving together. Additionally, their small size (around 2 inches) makes them perfect for my 20-gallon tank. They prefer a well-planted environment, which I’ve encouraged, and it’s been rewarding to watch them dart between the plants.
While I did notice they can be a bit shy initially, providing plenty of hiding spots helped them come out of their shells. I highly recommend these fish for anyone looking to enhance their freshwater aquarium. They’re a joy to keep and have brought so much life to my tank!
