Hi Truck,
Your probably well aware that I have one in my nano from the pics
As you can see I dont hide mine away. IMHO they dont need to be shoved in caves where their full beauty cannot be appreciated.
The only problem I find when someone new aquires this species (Tubastraea) for the first time is the problem of getting it to open.
This I put down to flow rather than squirting food around it. I remove the flow from mine and wait a while then I turn on the flow again, seems to do the trick.
As for feeding I only spot feed mine 3 times a week, which I feel is adequate as it is producing more and more heads.
I feed Live Phytoplankton, Live BBS, Frozen Cyclopeeze, Mysis shrimp, Krill pacifica and Brineshrimp.
Beware not to overfeed as this will play havoc with your Nitrate and Phosphate levels.
All in all they are pretty easy to look after and are a beautiful addition to any reef aquarium.
Hope that was of some help
Regards
BigC
