YES! THANK YOU!!! I should have checked local aquarium stores before thinking of the cat med solution! Google gave me Drontal as one of the medicines that include Praziquantel. I thought of the above as I periodically give my cat Drontal, but I'll definitely prefer esha gdex if the problem reoccurs. An aquarium specific med is what I'll prefer if it comes down to it.

Thanks again!

Just an update on this, the problem was temporarily fixed with gdex and reocurred. After coming back from holidays I found only one shrimp and the nerite snail alive. The last remaining shrimp in the bowl was heavily infected and a second round of gdex did partial work. Then I tried aquarium salt dip for 40seconds, on the 1st day 1 teaspoon per cup, second day 1 tablespoon per cup. After the gdex dosing cycle ended, the shrimp looks totally clear. So for me it was the combination of methods that did the trick.

So sorry that you lost your shrimp. I've saved your feedback so that the next time this happens, I'll have a better answer. (I confess that I was grasping, since I have no experience with this dreadful disease.)

It will be interesting to see going forward if your last shrimp is permanently cured. I wonder if the treatments killed all the parasite eggs in the tank?

The ultimate cause of the problem could be a genetic problem of the shrimp, environmental stress, or an intractable pathogen. I lost my shrimp one-by-one to what I think now was the buildup of plant allelochemicals. It may take awhile for you to sort out the ultimate cause of the problem.

Thank you very much It was sad to see most of them missing, but no worries though, I did learn during the process anyway, so I'll be better prepared in case is comes up again!

In addition to what we already discussed, I believe you are right about the environmental stress. I didn't mention about the temperature and light cycle factors. Here in Greece it has been really hot during the summer, meaning room temperature fluctuates between 27-30C (80-86F) from day to night, during the day being 29-30C (84-86F). Since these values are room temperature, they are tank temperature too (outside temps are a lot higher). The timer sets the lights for 8-2-4 hours on-off-on respectively. Maybe that was too much light for the shrimp, given that there are no really dark places to hide in this 1 gal bowl. Therefore I think that the shrimp might have been stressed due to the high temperature and lots of light, so maybe they didn't respond well to the initial treatment (gdex on its own). Perhaps that's why there were casualties while I was away too. My brother did feed and do water changes, so it wasn't totally neglected.

The single remaining shrimp (dark red male) looks totally clear now. He has no signs of infection any more, so I moved him to the 4gal tank to be with the rest rcs and the amanos. I'll watch them closely to monitor any signs of the disease occurring and act accordingly. I did a 90+% water change at the bowl and introduced new shrimp there (blue velvet/dream), which were drip acclimated with the same fresh treated tapwater that I filled the bowl with. I am now leaving the bowl light on for 8 hours, while the rest of the day it is just ambient light from the room that reaches the bowl. I am thinking of getting some dritwood, chollawood or coconut to make a hide for the shrimp just in case. Maybe that was the reason they haven't been breeding at all...

In conclusion, I believe it was the high water temperature and too much light that might have weakened the shrimp and made them more vulnerable to the disease. The salt dip (1tbsp/cup) proved effective in combination to the gdex treatment (made according to the instructions leaflet). If anything new occurs I'll post updates, but hopefully I won't have to!
