Received the X-Ray Fork Tail Tetras in excellent condition. They were active and colorful from the start. The forked tail is very noticeable and adds a unique touch to the tank. They get along well with my other tetras and are easy to care for.

The fish arrived safely and looked healthy. The forked tail is a nice feature. They settled in quickly and are now swimming together in a group. A bit shy at first, but they’ve become active and vibrant.
