I love my BTA. She (yes its a she) is beautiful. She picked a spot in my tank two weeks ago and has stayed put, happy every day. But starting yesterday she started moving. She started going under one of my larger rocks and moved all the way to the back. Now I cant really see her and I have no idea why she moved! My water parameters are good, nothing has changed and both of the clowns host it. Any insight into why she moved?
