Other Details:

Because it has been noted that amphipods predate upon larvae and eggs of this species I have taken great care to avoid cross contamination, a worm trap has been inserted with a small amount of pellet food to entice and capture any amphipods that may make it through.
The tank being used is the one I attempted to try for Americamysis (Mysidopsis bahia) and I have screened the overflow on the Berghia side with 100um mesh, the other side is filled with rock rubble (added dry) this is where my aiptasia culture is currently being performed. The idea is that when stimulated to release planulae the airlift overflow will pull smaller planulae into the Berghia side for the juviniles and larvae
