I've kept zebras before and they are nice, but I have never tried them in a community aquarium. Right now I have a L-134 and it is really a beautiful fish. It also has no trouble competing for food.
the people I ordered then from said not to add water from the tank to water from the bag because of built up amonia in the bag or some thing like that so I let the bag float and when the water was the same temp I took them out and droped them in the tank. They almost didnt survive and had a rough couple of days afterward. Are you sure I can add water from the tank to water from bag?
