Julio,
I can hook you up with some Aiptasia that are the food for the Berghia. The little anemones that look like BTA's are Majanos, and the nudi's won't touch them. Do you have any Berghia yet, or do you have a source? I have been trying to breed them for months now with no luck--I get them to lay eggs, the eggs hatch, and the babies die almost immediately. Haven't figured out what I'm doing wrong yet--maybe not feeding enough. I'm going to try a few different culture methods with my next batch.
