BTA and lighting question

[Coralgurl]

He sat lower to the bottom. Was an 18" deep tank, lights were 6" above. When I moved it to the 180 gl under radions, he is higher up, middle of the tank. When I got him, he was maybe 4" across fully expanded. He is now well over a foot big and still growing. I have another rbta that has split, both are at the bottom of the tank.

if lights not enough for a BTA could you supplement with direct feeding?
