I lost my rbta a few weeks ago and figured he found a nice place in the myriad of opening and caves in my rockwork. I was wrong. I cleaned out my XP3 tonight and found a blob attached to one of the media baskets. It stumped me as to what it was but I took a chance and carefully pried it from the basket and placed it on my closed loop. To my surprise it is the rbta. I have no clue how he got through the tiny openings for the XP3 but he did.
I hope this little guy makes it.
