I've had a BTA in my tank for about 4 months. It settled in the back of my tank where I can't see it. I've read a few ideas like using a power head, but has anyone tried shading it with a rock to where it might creep up to the top of the rocks to access light? I don't want to upset it to the point it starts moving around the tank. I just want it to creep up to the top.
