I had a population of these start taking over in my tank, I stopped broadcast feeding, switched to pellets and only would drop a few in at a time until the fish stopped eating.
The snails eventually starved. I also would constantly crush the bases of their tubes so they'd have to spend energy on building a new one.
It took about two weeks before I stopped seeing new tubes. Now I don't have any in my tank and resumed my normal feeding habits.
