These fish are peaceful and easy to care for. I kept them in a 50-liter tank without a heater, and they’ve been thriving for over six months. The red and gold colors stand out in the planted area, especially during cooler days.
Irene Hill –
Great first schooling fish for beginners. The long fins add a beautiful movement to the tank. I have six of them now and they swim together in a calm, harmonious way.
Eric Sharp –
They do well in a cool, unheated tank. The coloration is subtle at first but becomes more vibrant as the tank stabilizes. I’d recommend a group of at least six for best results.
