How Much Fenbendazole?

How much Fenbendazole should I use to make sure I kill all the possible lingering brown worms and planarian or any other nastiest in my tank without harming any possible saddled or almost berried females nor my month and almost a week or two old other frys?

The female I think is close to burying is in a breed box but one in the main tank might also be. Also The frys are mostly contained in an HOB breed box tank, tho there’s a few probably that escaped and also some regular adults in the tank. Here’s a pic of the tank,and yes I know the water level is low in the pic but has been filled now: (click for closer view)

 

Giving this a bump up for you

 

Females before berrying (they shed, mate with a male, and pass the eggs from their saddle to under their tail) need to be in a male's presence.

Do you have straight fenbendazole or is it a part of wormer?

I use a dog dewormer for dealing with planaria, I mix up about a half cup of water with about 1/5 of a 1 gram packet and treat 3-4 tanks with a pipette. To make sure to get everything, 24hrs later you want to do a second dose. I have shrimp in these tanks so I am very careful. For one tank 1/20 of a gram packet should work.

It’s a dog dewormer. Safe-Gaurd 4



Now my fry are in the HOB but it has netting (part of old hosier lol) over the intake and outflow to catch any babies that get pulled out or purposely swim past the barrier bars and I find it help less bad stuff get into the water because it has essentially a filter layer where it pulls the water in.
Also I have two “honeymooners” in a floating slotted breed box.
Would either of those situations change the amount or way you would add the fenbendazole mix?
I only found one brown worm when I was doing cleaning of the “honeymoon suite” and the HOB box, and not a whole lot of planarian but enough to make my smushing spoon twitch! Lol
I didn’t do a lot of vacuuming of the main tank so there could be more brown worms hiding in the bottom which is why I’m still considering using the parasite killer. It won’t make my females infertile will it? And should I remove the charcoal and filter or bio-wheel so it can’t kill all the B.B.?

 

It shouldn't as long as you have normal flow in the tank. If you don't have normal flow (so that there is movement in the tank, visible) you will have to swirl the water as you add the dewormer to make sure it disperses everywhere and is quickly effective.
Remove the charcoal if it is less than a month old, it will not hurt the bb.

Thanks very much! There’s a lot of water movement in the tank as there’s a hob filter as well as a in tank filter both that waterfall as well as a long bubble bar that the shrimp seem to enjoy greatly
Thanks so much you’ve made me feel much better about where I go from here and what I need to do.
