how big is your tank? I dont think my 25 gal is big enough for anything more than a single con pair. I know its a small tank for them, but its the largest tank possible for me. is their any more common fish I could use as a target/dither? my LFS has a very limited choice of fish. in fact, my cons were the first cons I ever saw at that store. thanks again for the help
My tank is a 29 gallon. You could probably pick up a giant danio as a dither but Striped Anostomus are fairly intelligent and can hide in the tightest places out of sight. When my Convicts are in crazy breeding mode, he hides behind the filter intake. He doesn't hurt any of the fry either, but he might pick one or two off when they are really tinly. Here's a picture of him.
