This anemone has grown well in my 30-gallon tank. It’s vibrant green with long tentacles and looks great in the low area. It’s not overly aggressive and doesn’t harm the corals. Needs moderate lighting and stable water flow. Easy to maintain once set up.

I’ve had this anemone for about six months. It’s active and colorful, and it’s adapted well to the moderate light. I noticed it gently touches some polyps occasionally, but nothing damaging. Good for intermediate reef keepers.
