The Blue Steel Killifish are stunning with their iridescent blue color and flowing tails. They’re easy to care for and stay active even in a small tank. I’ve had them for three months and they’re still vibrant and healthy.

Great addition to my community tank. They don’t stress other fish and are very active. The color is bright and eye-catching. I love how they swim in the background and add a nice visual element.

They arrived quickly and look exactly as described. The fish are calm and colorful. I keep them with tetras and they get along well. A bit shy at first, but they settle in after a week.
