My maroon hosts both a LTA and a BTA.. he goes back and forth, but he prefers the LTA
IMO get a LTA or BTA.. it doesnt really matter which. If your clown is hosting a shroom he will probably host either anemone.
Most importantly, buy only a healthy specimen. If it takes you a while to find a nice healthy one then just wait for it. It really sucks to bring a bleached nem into your tank, and watch it die while your clown swims around confused
Good Luck!

heres a pic of mine in the LTA. The pic got a little fuzzy because he was defending the nem when I was trying to shoot the pic lol
