They are funny creatures in the aquarium, my parents have one that has split twice now and has been pretty happy. But, they also bought a green BTA at the same time that only lived a couple weeks. I'd love to have one as I think an anemone hosting clowns is about as cool as it gets in a nano tank, but I have to move the whole tank across the country in a little over a year, so I am not sure I want to deal with that. Especially if I wait a good amount of time to add the BTA, it will only have a few months or so to adjust to the tank before it moves anyways. Maybe after the move, or if I can find a rescue like you did!
man i was totally hoping my clowns would like it, but the most they've done was look at it. i gave up on that and ended up getting the shrimp instead.
