Flatworm ID - During FALLOW Period

SimplisticDesign · May 30, 2024

Recently got ich in my tank, and my LFS has been generous enough to take in my fish.

It's been day 37 and today I noticed a lot of flatworms. Looked at many forums and unfortunately I do not have a microscope but will be taking to my LFS for a better ID, but for now can anyone potentially ID ?

Those are Acoel flatworms, probably what we'd call Ghost Flatworms (Amphiscolops sp.) - they're about as harmless as flatworms get, but it's still generally recommended to either remove them or get a fish that'll eat them.
