Mine was bought at a reef show, and was in medium health, got her home and all she wanted to do was inflate and get thrown around the tank, and it is an SPS reef with a ton of current, so that didn't go well.
Nem ended up in a WP40 and pretty cut up, moved her into a isolation basket right under an 8 bulb ATI full of Blue + and a fiji purple and coral +. She slowly got her foot sticky, and I would put rods reef and smaller mysis right onto her, and eventually she started to eat. Slowly but surely the tentacles got stickier and the foot stuck to the isolation basket.
Then I caught my clowns and put them in, they have never hosted an anemone, and it took them a while, but they figured it out. More feeding, more waiting.
Finally, I figured it was ready, it was eating, stickier, and a month had gone by. It was all healed from the powerhead incident. So I peeled it VERY carefully from the basket (ice cube trick worked well) and popped it on the rock I wanted it on. She snuck into it pretty far with her foot, tried out two different sides, and settled in.
Now it has been about 6 months and the nem is doing super. It eats about 1 silverside a week, loves the light (but lives in partial shadow), loves the flow, and loves its clownfish.
It also loves anthias and gobies, so far I am down one of each...
Definitely one of my favorite creatures. I look forward to a long time with this nem. Hopefully the clowns start to spawn. Most of my large SPS colonies are at the front of the tank, I left the back largely bare so I could relocate frags as the nem grew or moved. So far so good!
