As some of you may remember I had a cray infected with white worms, and the tank itself was infected with planaria and plant worms. Well I decided to dose the tank with Fenbendazole to kill off the planaria and plant worms, hoping it would maybe take out the white worms on the cray. Well I didn't think this was going to work because it had been almost 2 weeks since I started the dosing and as of 3 days ago he still had some worms (about half) still on him. So today I was gonna get him out to give him a salt bath and I can't find a single worm....
It seems to have worked and not a single loss. no snails loss, no shrimp loss, no fish loss, and best of all no cray loss.
Here was the dosing schedule
55 Gallon tank w/ 2 full grown crays, 5 or 6 Cherry shimp, 20 feeder guppies, live plants, and about 40 snails.
So all in all I have to say slow but very effective. I will keep people posted if any of the critters I was going for the kill on resurface.... and tomorrow I will do a 30% water change.
One note make sure you remove your carbon before running this medication.

- Day 1: Started with the recomended dose of .01 grams per 10 gallons No impact at all in 3 days
- Day 4: Doubled the dose Planairia and plant worms started having issues
- Day 6: 30% water change 50% of planaria and plant worms dead most are real sluggish. No impact on the worms on the cray.
- Day 7: Added another 1 gram for a total of 2 grams now at this point minus what was removed from the water change.
- Day 10: No sign of planaria or plant worms to be found still about 1/2 of the starting # of worms on cray.
- Day 12: Worms still on the cray
- Day 13: Worms still on cray but not as active
- Day 14: Went to get the cray out to go with the salt bath method and I can't find a single worm on the cray.....
