Congrats! False percs are weird like that. I love watching my perc in it's RBTA. My other perc (in a different tank) takes no interest in it's RBTA, go figure.
Mine took about 4 months. He's a false perc too. I pulled them all out to do hypo for ich. Now I hope he doesn't forget to host in his anemone when I put them all back in!
mine still haven't figured it out! They were hosting my feather duster, but I took that out like a month ago and they still hover around where it used to be. I'm still keeping my fingers crossed that they'll host the BTA.
