I’ve been an aquarium hobbyist for over five years, and I just received my order of 6 X-Ray Tetras (Pristella Maxillaris) last week. From the moment they arrived, I could tell these little guys were healthy and vibrant! Their shimmering bodies truly live up to the name ‘X-Ray’—the way they catch the light is absolutely stunning. Compared to neon tetras, these have a unique charm with their translucent look.
I placed them in my community tank, and they immediately explored their new environment, darting around playfully. It’s so heartwarming to see them interact with each other. They are peaceful and get along well with my other fish. After a week, they’ve acclimated perfectly and are already showing off their colors more vibrantly.
The only minor concern was that they took a little longer to eat than my other fish, but I soon realized they prefer smaller flakes. I would recommend these lovely tetras especially for beginner aquarists or anyone looking to add a splash of color to their tank. Overall, I couldn’t be happier with my purchase and will definitely buy from this seller again!
