The Pink Tail Chalceus are a beautiful addition to my 30-gallon tank. They swim actively in groups and their pink tails stand out beautifully against the silver body. Very lively and easy to care for once the water parameters are stable.

I bought a small group of them and they’ve been thriving for over three months. They form a tight school and add a lot of visual interest. Just make sure the tank is large enough to accommodate their movement.

The fish are vibrant and active. I noticed a difference in color intensity after a few weeks of acclimation. They seem to enjoy the current and swim in coordinated patterns, which is very pleasing to watch.
