i keep finding twigs in the freeze dried tubifex! wtf? will it hurt the fishes insides as it passes through?

hmmm im not so sure about that but i think id try to
take most of the twigs out just incase...

Are you sure it isn't larger tubifex worms? With my cubes, if you look closely, the top of the cube has smaller worms and the bottom of the cube has the larger ones.

But if it is twigs, (I'm not really doubting you) I'm sure it's not that dangerous to the fish. But you can take them out if it makes you nervous or they're big chunks.

in my tubiflex worms i also saw these but after looking very careful they seem to be dried more than the others which make them harder.i would examine carefully and if its wood take them out and send it to the manufacturer with an explanation.
