I have yet to read anything that sure a true fact of how to get them to do it. There are a bunch of theories, but not a true fact. I've had clones (of each each) were one had bubbles and the other did not. They were within a couple of inches from each there.
Thanks! I've been trying to increase the flow to help it bubble, but if I put too much flow on it, it just moves away from it. I've also been trying a scwd to change up the flow and it seems to love playing in the flow but no bubbling yet.
Oh and by overfeeding it, how much? I feed it a cube of krill about twice a week and it seems to enjoy the spirulina flake food I've been feeding my Maroons.
I don't think more light will make it bubble. My BTAs used to be under
3 * 96 PC (in my 58g), when I upgraded to 2*175 MH + 2 *96 PC, I didn't notice any difference. (that was the only change to the tank at that time)
