I have two tanks next to each other, one has my axies and one has celestial goldfish and blackmoors. Recently, I've noticed both have got a few thin, red worms in them. The longest are about an inch long.
Where are these coming from? How do I stop them and are they harmful to my axies or fish?
Thanks for your help
