the flow or light could not be enough for it. let it do its thing, but keep an eye on it until it finds its spot.Really, Ive been trying to get it to stick ever since Saturday.
yesterday, i bought another RFA and placed it in a spot i wanted it in. i look away for 1 minute and it was on the other side of the tank. it attached to another spot and kind of held it there or about a minute or two, it managed to stay there.
