I feed my fish frozen bloodworms from time to time and the bottom dwelling ones never seem to get any because the worms will not sink.. what can be done to get them to sink>?
I find that if i thaw them out first by floating the cube in a small cup of tank water the worms will sink easier, and my bottom dwellers get to share in the feast.
I tend to rub the cube between my fingers just submerged in the surface and the bloodworms will sink but may not make it in time to the bottom of the tank before getting eaten!
