Sea Pen

[odf94]

Saturday I got a sea pen,which I am struggling with.. I placed him in a 8" PVC tube the first day it was perfect,he stood up and everything...I did also fed him with mysis shrimp..

The second morning I found him in the middle of the tank between other corals,stuck.I took it back place it back in the pvc but now,he is not standing up anymore it is opening.. but it is not standing..

Any idea? what's wrong with him? What might be causing him not to stand up like he did few days ago?

I appreciate all your advice and help!
Thank you

Feeding. It's a filter feeder that relies on marine snow( dead organic matter) and small plankton. Mysis is too big and it needs food if possible constantly.

They're not easy to keep. They also require the correct water flow and high quality water params.

You won't be able to keep a sea pen in a small piece of PVC like that. They need a wide, deep sand bed to move around in. It needs to be deep enough to bury the foot completely and to provide leverage for when the colony bends over one direction or another, or decides to relocate itself. I'd say a depth of at least 6 inches, preferably of fine sand or even miracle mud.

As Nemato mentioned, mysis is too large for them. You may see a response from the coral, but it can't effectively catch and digest mysis. Frequent small feedings (meaning a few a day) would be best. I've had good results using rotifers, powdered food (New Life Spectrum fry food works well), and zooplankton up to the size of copepods and brine shrimp nauplii.

Overall, not an easy thing for most people to keep.
