I think you'll need to move your shrimp to do an effective treatment to your main tank.
IMO, your best options would be either the Coppersafe or heat/salt method. You would need to do it for the full 21+ days to completely go through the life cycle and knock it out.
As for the shrimp, ich isn't known to be a problem with them, so if you keep them in a different tank during treatment, the ich should not be present on them anymore, so you should be able to safely re-introduce them back to your main tank after you've treated it. |
