Do you simply use your hands and break it from the base of the branch? I originally tried to clear as much of the slime as possible but left a few bulbs because I simply couldn't clean the whole thing up. Now, the few bulbs that I left have reinflated again and look healthy. However, it looks like I just lost another one so I'll probably break that one off tonight.
As for the flow, the flow is very gentle so I don't suspect that that's a problem. The clowns also don't try to host it as they seem much more interested in the frogspawn. But I supposed I could have accidentally bumped into it while working in the tank or something like that. Regardless, I will try to break off the branch.
