Hey guys, I have a little problem in my aquarium this week. About a month ago, I decided to get my hystrix some feeder shrimp, for the first time. I put in 10. After eating 8 of them that day, he seems to have suddenly decided he doesn't like feeder shrimp anymore. The remaining 2 have grown to about 2 inches now and are going after the discus in my tank! They have torn the fins of a couple of them. I can't catch them without distressing everything else in the tank. Can anyone recommend a better way to get them out?
