Ok. So after one of my tiger barbs died due to a fatal attack by another barb, I went to go buy two more. I have a total of six barbs. One thing that I noticed after the death of my barb was that one of the other barbs seemed to swim alone, away from the group. I think he might miss the other barb for some reason and so he swims alone. Just recently the other barbs have been picking on him and they've nipped his fins. Now I don't want the same thing to happen to this barb and I was wondering how I can divide the tank quickly before I lose another barb. I've went to my local
LFS but they don't have large enough dividers. Is there a way were I can make my own net? I don't really want to set up another tank for just one barb. Please help. Thanks.
