Just to update this thread/add more information....
I have used Fenbendazole (dog dewormer, 22% Fenbendazole) to treat a *tiny* outbreak of scutariella in a tank. Rather than doing a salt dip on each individual shrimp I saw with the parasites, I chose to treat the entire tank. Worked like a charm! I did a half dose at night, then the other half in the morning, of 0.1 gram per 10 gallons. Made the tank a milky cloudy color, and the shrimp even ate some of the Fenbendazole, but seemed unaffected by it... scutariella were killed off at least, and no further treatments were done.
The liquid suspension sold for goats or Fish-Bendazole will also work, however they have different doses per 10 gallons.
As far as ellobiopsidae go... there is hope!!!! This this is a parasite that attaches to the outside of the shrimp and forms "roots" into their carapace (if my understanding of how they grow is correct... unless it's an internal parasite that burrows it's way out... also possible?), we need to treat it like an internal parasite. It may sound odd, but apparently the best method may be medicated food using products like Kordon Rid Ich+! Article here....
