How Do I Eradicate Hydra Not Responding To Fenbendazole

I treated my five gallon betta tank using fenbendazole. I researched dosage and mixed 1 gm fenbendazole with 10 oz conditioned water , shook vigorously and added 15 ml to tank. My tank has hydra all over walls and plants. No sign of change in hydra, so after 24 hours added 15 ml fenbendazole again. Still no change next day. My betta looks good. Did remove charcoal filter. What am I doing wrong?

 

Works great for me, and I just last week used it on some of the huge white ones in my fry tank... Couldn't tell you exactly what I dosed but probably around 2 grams in a 10 gallon tank. I used Panacur this time. Killed them first dose.

 

the stuff works great, I tried fenbendazole and didn't like the results.

Thanks for your response.
Just to clarify, you used 2 grams (2 packets/ 1 Gm each) and it didn't harm your livestock?

Packets I got were 22g a piece, I added 40ml of water and dissolved the best that I could in a dish and used a syringe and pulled 2ml out into the syringe and dosed the tank... Not real scientific measuring and not very precise I'm sure. But it worked with no ill effects.
When I've dosed in the past in tanks with hob filters I have divided up the packets (varying amounts) while dry into tiny portions I estimated at 1 gram apiece and stuck it to the back side of the sponge while dry, that has worked for me too.

 

What I did was a bit different.

You first want to measure out the fenbendazole then manually grind them into powder. Then you add drops of water at a time, mixing it into a paste, then soup, and finally just a cloudy white water. Afterwards I added it directly to the tank filter flow.

I actually tripled the dose without any sign of health issue to my fish. Snails took a toll though, but I don't care for them. After 48 hours, no hydra. I did a massive water change. Two 80%-90% water changes. Then I added activated carbon.

This WILL kill the hydra. But probably kill all the snails you have too.

I just took my betta out of the tank and tripled the dose and put flow on high. I will let you know if this works for me.

The tank was so full of h

I ended up dumping the rest of the bottle (total 1 gm) in the tank. It looked like the hydra might be dead but they were still clinging to the glass and plants. I took down the whole tank. I bleached the tank/gravel/decoration. I soaked the plants in refrigerated spring water (suggested by local PetSmart experienced seller of fish) and set the tank up. I hope what I'm seeing on the plants is DEAD hydra corpses. Time will tell.

 

Wow that was one tough hydra.

Lots of water changes. And it could be fin biting too. If you post a pic in the betta section of the forum people can help you decide. I have a fin biter and one that gets fin rot to the drop of a hat. Lots of water changes for fin rot, tail biting in this case may have been stress from being moved, neither are serious.

Thanks, you are nice to reassure me and give advice.
