The Klasio Creek fish are very active and colorful. They adapted quickly to our tank after a week. The red and blue colors stand out in the aquarium. Easy to care for and very peaceful.
Benjamin Black –
Great addition to a community tank. They stay active and don’t stress other fish. Water parameters were stable after a few days of acclimation. Slightly shy at first but became confident over time.
Ella Wilson –
Beautiful fish with vivid coloration. We’ve had them for three months and they’re still healthy and lively. The flow in our tank matches their natural environment well.
