Well I went and did it. I got 12 of the smallest barbs you can imagine and stuck them in the barb tank a couple of hours ago. By small I mean the largest one is maybe a 1/4 in. They are the cutest little things and only cost me $1.00 each (on sale) instead of almost $2.00. All are really nicely colored and ate like the pigs they are. I also got a top for the tank. I'll get pics and put them up when I get the FTP to work. Rose
