Is there anyway to make this attach to rock? I want to put some in my empty fuge, but the flow is too high where it wuld just float to the top and clog the overflow.
if not rock, any other way to get it stay on the bottom?
If chaeto is stationary it will grow, but it will become a detris trap and die on th bottom. When I was in Hawaii last year I saw chaeto as big as pillows just floating around. IMO it does best with enough flow for it to tumble around.
