Crawdads after velvet

Hello, and thanks in advance for the help

I have a 10 gallon tank that had 3 chillids iin it with 2 crawdads. 10 gallon Walmart tank kit with charcoal filter, 50% water changes weekly. Jungle start right water conditioner was the only chemical used. Tank was running fine for 4.5 months then I added to small algae eaters which died within a week. The chillids then started surface breathing then when out of town wife saw fish with yellowish coating then all 3 died, I am assuming velvet disease.

I came home and removed the crawdads to separate containers so I can clean the tank. One of them has eggs attached under the tail! My next move is to strip the tank and clean everything with diluted bleach solution and rinse, rinse, rinse to prepare for more fish in near future.

After all the back-story, my question is will I be able to reintroduce the crawdads to tank with fish or will they still be carrying the disease?

in theory yes...but you do know that the protazoan parasite will be present in the water as well as on the crayfish...this means the holding tank will have it as well but there will be no fishes to may be able to get away with it if you alow the parasites to starve off ...i am not sure if there are any crayfish safe medications...good luck...

Got the crawdads in 2 containers with gravel today. I can now see worm-like parasites clinging to the crawdads and moving around the tank. They are a light brown color and about 1/8 inch long and about diameter similar to a strand of hair.

Is this the free swimming stage of velvet disease or something else?

doesnt sound like velvet...its probably a one of many nematode looking creatures that can be harmfull but usualy graze on the surface of the host crawfishes body...i asume this craw fish is wild caught...they tend to bring all sortsa unwanted invertabrates with them...
