Some of these types of critters can't complete the moult without iodine. 
If you can get ahold of any kind of marine aquarium iodine supplement 
dose that at half strength. According to Az Aquatic Gardens this is the 
way to go, dosing either one time a week at half strength or full 
strength every other week or after water changes. I use Kent Marine's 
version, though there are many and chemically they should be about the 
same. Lugol's from the pharmacy is overly strong, the stuff for 
aquariums is diluted and of course more costly.
I don't know if the one which is stuck will make it but I would isolate 
it til it does so it doesn't get picked on. Even if it doesn't make it 
the other as well as any aquatic shrimp will benefit from this nutrient.
Anyone know if plain old iodized table salt at a tsp/gallon would cut 
it? I use non-iodized salt and then dose with iodine, maybe I don't need 
two products...
