I have found scuds to be a challenge when trying to eraticate them. I had them in my 1.5 gal shrimp tank. I tried various fishes, some - like the gouramis will keep them in check but they do not totally get rid of them.
I also tore down my tank and boiled the gravel and bleach dipped most of the plants, ans scrubbed down the tank, filter, and everything else. They still came back (i suspect the HC was hiding some). They survived several weeks in a uncycled tank with the ammonia,nitrites being very high.
I ended up ditching any plant that could not be bleach dipped and freezing the tank and gravel and filter.
Good luck on getting rid of them!

I had read a posting on another forum that they will attack baby shrimps, that is why I had to get rid of the ones that were in my tank.

This is what dhavoc on the planted tank forum stated about scuds.....
"you dont want to mess with them. yes they are easy to breed as feeders, but they are also IMPOSSIBLE to eliminate from any tank they are introduced to. and remember, they are plant eaters (especially mosses). and the big negative... if they cant get enough food, they WILL become carniverous, they have wiped out my opae ulae tank (yes they can adapt immediately from fresh to brackish water). they also will attack newly molted shrimp.

they are not worth messing with, go with daphnia if you need a live food source. scuds are just too hard to get rid of. "
