Taking an opposite tack, here, I am looking for something in which to feed my blue damsel to.
It's a mean little bugger, but I have had it longer than any other fish, so I am also attached to it. I lost count of the tank mates it killed by stressing them out.
Before anyone says anything, I got it over 5 years ago at a LFS... for $16! I've learned alot since then, thanks to this site and a reputable LFS.
