JoaquÃÂÂn,
It is very good to hear from you, my friend.
The symptoms that you are seeing with your corallimorph cannot be directly attributed to allelopathy in my opinion. In deed, coral aggression is always an issue, but the sudden onset of a brown jelly infection is far more indicative of excessive mucus, inadequate water flow and/or higher dissolved organics in the water (water quality). The other coral species are simply more tolerant in this case.
I would suggest trying great er water flow and adding small daily doses of iodine to spike redox if not proffer some antiseptic qualities (possibly). Try single radial cuts too from the mouth outward. Just one at a time to induce a fissionary split for the polyp on its own in just a couple weeks.
As far as Mazatlan, I am very dissappointed to say that we did not make it to Mexico! I was looking forward to it very much.
Bob Fenner and I had sent repeated messages asking for information about the event and our arrangements. The only reply we ever recieved was the same message over again about requests for our lecture paper (length, spacing, type, etc). We even enlisted the help of two different translaters to send messages in fluent Spanish on two occasions asking for contact info.
Alas, there must have been a communication or organizational problem on their end becuase we were not called until 2 days before the event! They wanted us to come down still but we had no travel tickets, contact or itinerary to follow. They simply weren't organized or prepared to bring in speakers it seems.
What a dissappointment... I have heard such wonderful things and I have never had the pleasure of visiting Mexico yet or sharing meals with new Mexican friends
No worries... one day it will be so.
Best regards,
Anthony
