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!

I have used dosages of aquarium salt and peroxide to kill off both planaria and hydra in the past without any problems to shrimplets. Just pointing out another potential option......

Nice article, Matt!

I have tried this in my 20g shrimp tank that house's tiger's, yellow's, mts and some minami's. I followed Matt's procedure with great success. It has been close to a month since the application and I have not seen a single planaria!!! All the shrimp didn't even wink at the medication. Thanks again for the information!!!

Thanks so much for this article! I have an older betta (4+ years) whose tank became infested with planaria and hydra after a plant purchase (this was before I knew about sterilizing). After just one dose, the planaria and hydra were gone. And my betta didn't have any problems what so ever!

I used Safeguard (brand of fenbendazole) today using 100 mg/10 gallons and one of my 7 embers died one hour later.

I notice that this thread is over a year old, but it was linked to from a different forum. Great information! Thank you for the great advice on hydra / planaria eradication. I noticed hydra in my 10 gallon RCS and tiger shrimp tank recently, but was a little hesitant to try fenbendazole because I have one month old baby otocinclus and MTS in the tank. After a couple of weeks of debate, I took the plunge and tried it last night. I've seen a range of doses, and I decided to go conservatively. I used liquid Panacur, which is a 100 mg/ml suspension. I used a dose of 25 mg (0.25 ml) per 10 gallon, mixed it in about a cup of tank water, then used a syringe to apply the diluted mixture to the affected plants and glass directly. The water turned cloudy pretty quickly, and the hydra almost immediately went limp. It is now about 15 hours later and the water is crystal clear again and most of the hydra are gone. There are a few hydra still attached to the glass, but they're limp and hanging upside down. There are no casualties as of yet (I'm knocking on wood). Baby otos, shrimps and MTS are all as happy as can be. I am not sure if I should re-dose in a few days or a week or so, or if this one low dose is adequate for complete eradication. I'm going to wait another 12 - 24 hours to see what happens. We shall see...
