The amethyst purple tube anemone is very active and shows interesting behavior, like grabbing fish food. It’s a striking addition to my 30-gallon tank. I’ve had to keep it away from small fish, but it’s a great visual centerpiece.

It’s colorful and lively. I noticed it moving around and interacting with food. The only challenge is its aggressive nature, so I made sure to place it on sand and avoid placing it near shrimp or small fish.

This anemone is a real showstopper. It grows steadily and stays healthy with proper lighting and flow. I appreciate the unique coloration and its active behavior.

It’s beautiful and active, but I had to move it twice because it was too aggressive toward my snails. I now keep it in a well-established tank with larger fish.
