I had a Maroon clown that was hosting a sebea anemone. I did not have enought light, so my anemone bit the dust. For the last three days of that anemone's life, however, I had MH, cause I learned my lesson.
Anyway, the dead anemone was all deflated and the clown was still trying to host it. It was pitiful. So I went to the LFS and bought a BTA. I acclimated it and as I have the anemone in my hand reaching down into the aquarium to place it, the Maroon clown dives into my hand and starts hosting right there. My clown would not even let me get it placed before he claimed residence.
