Gore15 Posted January 22, 2021 Share Posted January 22, 2021 During a nightly inspection I came across 3 of this entities. They open their petals (like a flower would open) and close on light change. For example if I shine a phone flash light on it it can close or open so light change make it react. I could not make a better photo but will try. My main suspicion is Aiptasia but it looks much smaller and I could not figure out if Aiptasia reacts to light like these ones are doing. If you can give any suggestion on what this is, please let me know. Quote Link to comment

Tired Posted January 22, 2021 Share Posted January 22, 2021 Yep, tubeworm. They retract when startled, and can be startled by light changes. 1 Quote Link to comment
Gore15 Posted January 26, 2021 Author Share Posted January 26, 2021 I wonder if this is going to grow big or they stay small? Quote Link to comment
