I received my first BTA yesterday from California. After being in my tank for a couple hours it looked fine but I noticed that it looked like it was tearing. I assumed it was going to split. Well last night it crammed itself behind my overflow and when I woke up this morning a quarter of it was torn off and in my overflow. So either it split or committed suicide. I always assumed they split nearly in half. Do they split smaller sisters? Is my BTA going to die?
