Vile worm ID
I just scored a really great setup for $65! A 55 g with filter, light, etc., etc., etc., and several fish. I wanted to get them back into their home, so I set up the tank again ASAP. The substrate is black gravel -- I want to change it out really soon. It was pretty dirty; it appears there is an UGF in there under about 4" of gravel. I am going to try to use a gravel vac tomorrow once everyone is settled in better. I noticed some really gross little wormy things in the water -- they're about 1 cm long and about hair-thin. They "snake" around through the water. They look a lot like heartworm microfillaria, actually. Are these detritus worms? Do I need to worry about them?
