Does anyone have any advice on how to cull red cherry shrimp? I started out with 25 in a 29 gal and now have them coming out of my ears. I really need to pull some out but would prefer to remove only those that aren't so red. As my tank is heavily planted, there is no way I can chase down any specific shrimp. The easiest way I can think of to catch them is to put some food in a net, wait an hour and pull a bunch out. But I would still need to sift through them for keepers. Any thoughts?
