Hey guys

So as some of you already know I am setting up a new aquarium and I want to make sure that everything I put in is pest free. I know this is mission impossible but I want to try my best, I am specially concerned with Aptasia and bad Asterinas as well as fireworms and anything that could kill or damage my corals.

I am a bit more permissive with regards some sponges, bristle worms, etc.

So on sunday I got a few zoas from my LFS.

I put the zoas on my quarantine tank and it has been there for a few days now. When I put it first in the aquarium I noticed that both side of the coral had a sticky spongy looking stuff that had some black gravel stuck to it.

As I didnt know what it was I decided to leave it there for the moment until I could have a proper look.

So today the first thing I did is put the zoas in some salty water with a few drops of Coral RX dip, inmediately I saw a bunch of amphipods, firewarms and a brown Asterina (these are known to eat zoas) popping out of the coral. I also noticed some bubble algae growing in between the polyps.

So my question is, what do you think the transparent jelly stuff is? (see picture below) The stuff is covered by some black gravel but you can get an idea (I hope)

The zoas are opening fine so I am not sure if I should remove or not as it might be part of the coral (although I doubt that)

Any suggestions?

Ok so I decided to open it up in the end. I read in a few places that the transparent stuff could be a fungus of some sort or at least maligne to the zoas. As I wasnt 100% sure I decided to just remove one of the two.

I cut the jelly stuff open and inside I found several brownish stuff





The suff was definetively alive but I am still not sure of what it is and if I have made a mistake by removing it.

I haven't removed all the jelly stuff however I found 3 kidney looking brown stuff like in the picture above which I think it should do the trick.

Any suggestions?

Zoas are back in the quarantine tank and they are opening fine. I might remove the other one tomorrow but I rather wait for your opinions!

Thanks

Ok so I also removed the other "thing" from the other side of the rock and all the transparent jellyish stuff is gone. The zoas are still inside the quarantine tank, its been there for a few days and I havent seen any bubble algae grown nor any Asterina. However, this morning I did spot a tiny aptasia growing beside one of the zoas... so now I will try to remove this one using aptasia X and leave the coral in quarantine for another 2 or 3 weeks...

So, in conclusion, so far I have found, fireworms, asterinas, bubble algae, two "things" which I am yet to id and aptasia....

Thats from a 10 cm rock.. I tell you I have learnt my lesson, no coral is going straight into my DP tank without spending a few weeks in the quarantine tank... :S
