I need to dose my tank for red bugs with interceptor and have been trying to catch my shrimp for a few days now. I have tried to do the water bottle thing with no luck, and have also been trying to net them at night with food and still no luck. I have caught all my crabs and one of the cleaner shrimp but I still have one more left and 2 more fire red shrimp. They are supper big and healthy and have been in the tank for around 2 years. So my question is does anyone know any tricks on catching these things, and if I cant get them out do you guys think they might survive?
