My Dracaena keeps falling over from the betta knocking it can I superglue a large flat pebble or slat to the centre of the root mass so that it has a bit more of a base to hold it upright? Anyone else got any ideas? The roots are healthy and I think they are growing as one plant is against the side glass and the roots have moved through the sand of their own accord but they are not strong enough yet to survive a head on collision from a betta swimming with the water current. There are 2-3 plants in the area that may get knocked over. I am going to get another bag of sand this weekend bring the substrate thickness to 1-2" whilst its currently 1-3cm
