Freeze-dried Tubifex Cubes

[Cheese Specialist]

Hello,

I want to feed my fish tubifex but I would like to stick it to the glass but I can't seem to do it!! It says on the container that they can be stuck but I can't get it. I have tried a few times. It will stick for a second but then floats to the top before the fish even notice it. I have tried squishing it against the glass but that doesnt work and I have tried not squishing it to no avail either.

Any tips would be great!!
