They tend to stick on the glass a lot. I have seen some gouramies eat them, but other than that, they seem to have no effect on the tank. I have come to associate the appearance of these worms with overfeeding, They won't hurt your fish. Controlling food levels and continuous monitoring of water conditions will reduce them to nothing. I think they are introduced in the egg stage with flake foods but I am not sure.
