I hatched out some mystery snails several weeks ago. I started noticing that they were dying 2-3 weeks or so ago. I only have a few left alive from that clutch. Anyway, their breeder box had gotten really covered with brown and green algae so I decided to clean it...especially since only a few snails were left alive in it. While trying to sort out the live
snails, I noticed a lot tiny red worms on the plate I was using to sort through the snails. I then started moving some of the red colored debris around and realized that the debris is tons of the red worms bunched together. Can anyone tell me if these are parasites or a result of the snails dying? If they are parasites, what are they and how do I get rid of them?
I have also had a couple of adult mystery snails pass away these past couple of weeks. I really do not want to lose any more. I have attached images.
