Nothing at all. I had moved it about 2 inches the night before but that's it. Only thing remotely close to it is an acan but even that is at least 3 inches away from this. I took it out of the tank and sucked everything off it and in amongst all this was some brown stringy stuff which is why I thought of brown jelly. At the moment nothing else seems to be affected. Took a good look at all my hammers and torches but they seem to be fine.hard to say from that pic, anything else look affected? Did anything fall on it?
I dip everything before they go in also. Dipped the Chalice the night it happened but found nothing out of the ordinary.This particular piece had been thriving for the last few months but unfortunately not much that I could have done. Crazy how quick things can go sour in this hobby. Thing the worst is not knowing what the cause was.The same thing happened to a lobo of mine which was on the sand bed. I took it out dipped it and 2-3 small shrimp like critters fell off along with a lot of black tiny moving spots.That didn't save it though cannot find any info on the pest type. It may be too late to save that chalice but try dipping it. If it was not near any other coral then it has to be a pest or a bacterial infection of some sort. I dip every new coral but dips will not get eggs which can hatch later
I have a Favia approx 5 inches away from where the chalice was so I'm sure it wasn't the culprit although thank you for bringing that to my attention as I have another chalice frag a lot closer to the Favia than it probably should be.I've never seen an Acan send out super long sweepers. Now a Favia or Favites will whack anything within 5-7 cm and don't get me started on Galaxea or Merulina, those are stone cold killers.
So fascinating to watch. Only been into marine 6 months and as a newbie I still question myself on where I need to place everything, not only so it's pleasing to the eye but also to what will be peaceful to its neighbor. I see so many beautiful tanks, some that look so jam packed and think how on earth are they all so close together and peaceful...Think I need to study a little more on each coral before adding anything else to the tank.I had a piece of Galaxea that would throw out 15cm long sweepers. Search coral wars on YouTube and watch what happens to some of the corals, it's frightening the amount of aggression there is between different species. Hydnophora is another bastard coral.
Always got to be careful with blaming bugs and worms for killings corals as they may just have turned up to dine on the tasty dying coral flesh and they may be what actually killed the coral.The same thing happened to a lobo of mine which was on the sand bed.
