Hello, just curious about general behavior of these guys. I got about 7 of them 3 weeks ago and they were hardly ever seen, hiding in plants, caves, rocks whatever, but i noticed my tank was a lot cleaner in the process. but i hardly ever saw the little buggers, now they are constantly swimming in the front of the tank swimming up the glass, and have no fear of my fish any longer they are always out and in the open, however still doing a great job cleaning, but now they seem like they are trying to be the center of focus!!!I thought they were shy creatures? Does any one elses shrimp act like this??? My amonia is 0 nitrite 0 other fish are all peaceful
