Reefing newb
I have a sea fan that has dropped his crown. I know that it is a sign of stress is there any other reasons? I know shrimp molt so I hope the same here. I moved him from a 20 gallon tank to a 55 gallon tank almost a week ago. Water prams are .5 ammo, 8.0ph, no2 .5 no3 5ppm. Now I am stressed
A lot of things can cause the worm to stress.But your water looks pretty good.
Is there anything picking on the worm?That will cause them to shed the crown.
From what I understand they periodically drop their 'crown' and grow a new one - mine did... nothing to worry about (unless it doesn't grow back). took a few weeks until it was back to it's full size.
