Anemone Identification

[fvlewg65]

I was in BA yesterday (sad situation) and bought a small anemone, I was told it was a red bottom anemone, however, I can't find any info on red bottom anemones. I think it is a Beaded anemone, but I am not sure. Can anyone help me to identify it please. It is my first anemone, so any additional info would be good also. Ie do they prefer to attach to rocks or hide in the sand. What do they eat? Basically how can I make it as happy as possibble to be in captivity!
