I managed to 'suck' up a bunch last night during my water change. I replaced the vacuum end of the python with the end of a baister to creat a hi velocity vacuum. It worked pretty good, however only on the larger ones. I found that in order to suck them from the rock, you had to hold the vacuum over them of about 10 seconds or at least until they let go.
I also purchased a half dozen peppermint shrimp to eat the rest... I hope.
