Re: Planaria and Hydra Elimination in Shrimp Tanks Thanks for the advice. The first dose got rid of 90% of the planaria and it took a few days. I just added a tiny bit more to the water last night to get the last few guys. No change in behavior in the fish or the shrimp. I have also observed the shrimp fry and noticed they were behaving normally. No water changes performed. Kudos to this article and the contributors! |
