Isaac Bond –
I’ve kept this anemone for six months in a 75-gallon tank with strong lighting. It’s visually stunning and adds a dramatic presence. However, it’s aggressive and I had to remove a small shrimp that got attacked. Only recommended for expert reef keepers with a large, stable setup.
Jake Parsons –
The anemone looks beautiful and grows steadily. I maintain high light and medium flow. It’s not peaceful, so I keep it in a corner away from other inhabitants. It’s worth the effort if you’re prepared for its behavior.
Simon Arnold –
It arrived healthy and has been growing well. I’m cautious about placing it near corals or small fish. The size is impressive, but the aggression is noticeable. Not ideal for beginners or small tanks.
