I have a 45 gal tank and made the mistake of making 3 blue damsels my first inhabitants about 6 weeks ago. I tried to put 2 more in yesterday but the originals murdered them in just a few hours. After researching a little (Shoulda done that first), it looks like there isn't much hope for me introducing any other fish without a repeat of this episode. Anybody have a suggestion on species or size that the damsels won't harass to death? Its a live rock, fish only tank.
