The Penguin Tetras are active and peaceful in a community tank. They thrive in soft, slightly acidic water with plenty of plants. The coloration is subtle but consistent. I’ve kept them for over six months and they remain healthy and lively.

They are easy to care for and fit well with other small tetras. The fish show natural behavior in a planted tank. A bit shy at first, but they settle in quickly. Good for beginners looking for a calm, colorful addition.

I bought a small group and they’ve been very active in the tank. The tank needs good water quality and some cover, but once set up, they’re a joy to watch. No aggression, just gentle swimming.
