How can I feed them? Directions say Press cube firlmy against side of aquarium... but it wont stay!

Not sure where they managed to do that...but it don't work. I just toss them in and let the splashing and sucking begin.

I suggest reading the link below before feeding tubifex worms to your fish.

My tubifex works stick just fine to the side of my glass. I just break the cude in half and then press the broken side to the glass and hold it with my finger for a couple seconds. I push really hard to get most of the air out of the cude and it ends up being almost flat to the glass. It works just fine for me
