Dont do a haitian. They are just like a condy and have a 50/50 chance of eating your fish. =\ I had one, and my false percs hosted it, and I regretted doing it. That nem was the biggest wanderer, and would never stay in the same place. I had to move all my corals around the tank to avoid it killing them. I would try to find some kind of BTA. Mine hasnt moved since the day I got it.
