It took a long time for my BTA to get happy, he had this perfect spot then the stupid ice storm game and I had to take very very drastic measures to save my tank. He then relocated. Luckily he has stayed at the new spot and seems happy. My RBTA could never get situated and my Koralia ended up eating it. =( I feel your pain Grins.
I know you do, my son has decided he hates the rbta..lol. I don't hate it yet, we just have a tumultuous relationship.
