Well you can see in the picture all the gunk building up in the substrate, thatís what theyíre eating. Like we said theyíre not harmful per se, just kind of unsightly and an indication that the substrate has a lot of stuff for them to eat.
Technically you could treat the tank with fenbendazole (dog dewormer) but that is likely to cause an ammonia spike because of rotting worms so I would be careful going that route. It doesnít address the core problem anyway.
