So I've noticed a few of my platties, my swordtail, and maybe my silver mollies have this reddish looking string coming from their body. At first I thought it to be fish waste, or maybe even a penis (
) but from what I've read it may be nemotodes, or camelanus worms. However, after a bit more research, it said these worms retract at any tinge of movement... these eventually fall up and get sucked off into my vacuum.
Do I potentially have a worm outbreak? If so, what can I treat with, that would be readily available at stores like petco?
