ID help -- 02/07/08 I recently picked a new piece of coral up. It is unlike anything I have ever seen. Here is a link to a thread with some pretty good pictures that I took of the coral. Please let me know what it is. http://www.reefcentral.com/forums/showthread.php?s=&threadid=1312909 <Wow, that's a tough one. The tissue makes it pretty hard to see the skeleton. My best guess is some kind of Goniopora sp. but I honestly can't be sure. Are there any dead, exposed parts of the skeleton you could take a picture of? If you could send that in, it would really help. Or maybe Bob has a better idea. If all else fails, you can always ask Eric B. Though I'm sure he'll likely also ask you for pics of the exposed skeleton for any proper ID.> Thanks Ian Iwane <De nada, Sara M.>

Re: Scler. ID help   2/8/08 Thanks Sara, There is no exposed skeleton on the piece. I was thinking last thing I would try to do is cut a little piece off and bleach it. If that was necessary. For a size scale, each polyp is around 2mm or so. Let me know if you guys have any other ideas. <Well, Bob doesn't think it's Goniopora, so I'm out of ideas right now. Having a clean piece of skeleton would certainly help if you think you can spare it.> Thanks Ian <Best, Sara M.> <<We'll see... RMF>>

Mmm... no... RMF

Re: ID help- Madracis sp? 02/19/2008 I updated a skeleton shot in the same thread. Take a look at it tell me if it helps http://www.reefcentral.com/forums/showthread.php?s=&threadid=1312909&perpage=25&pagenumber=2 <So sorry for the very, very delayed response. I was out of the country. The skeleton pics are very helpful, thank you. There's still too much tissue/water on it, such that the details/nuances are obscured. However, I can see enough to see why someone posted that it looks like it could be Madracis pharensis. I do agree it looks like a Madracis sp. However, I think it's more likely Madracis kirbyi. I say this because Madracis pharensis is not found in the Indo-Pacific (where most all our corals in the trade are from). Madracis kirbyi is found in the Indo-Pacific (one of the few Madracis sp. which are).> Ian

Re: ID help -02/20/08 I attached a new skeletal shot. The skeleton looks nothing like the kirbyi. I guess they have said that the pharensis has been found along the pacific coast of Mexico. Also my friend Norman (Mr.. ugly on RC) said that he read somewhere that it was also found in Hawaii. Not sure though. Take a look at the new shot at tell me what you think. <Ok, yes, that photo is more clear... but I still couldn't tell you for sure if it's M. pharensis or M. kirbyi. The two are just so similar. One would almost have to look under a microscope to tell them apart. You might want to ask Eric B. However, again, it just seems SO odd that a M. pharensis (which, according to Veron, is "rare except in caves") coral would end up in a US LFS. And the book doesn't include Hawaii or Mexico in its range. But even if it's true that a M. pharensis could be found in Hawaii or Mexico, that would still be rather unusual since we're not meant to get corals from these places. But maybe Bob has more insight into this.><<Mmm, no... not w/o more delving than I have resource for currently. RMF>> Ian
<Thanks for Sara M.>

Tiger Jawfish Keeps laying eggs, and unidentified coral 01/28/2008 Hi all, <<Hello, Andrew today>> It's been a while since I wrote last. I have a 95 wave tank with 48" metal halides (by orbit) it's also got actinics and moonlights. Everything is on a timer. I do regular water changes, about 10-20% every week. I supplement the tank with the following; Essential Elements (5 ml/week) Liquid Calcium (2 tsp/day) Microvert (5 tsp/week) Tech M (20 ml/week) Phytoplankton (10-15 ml/week) <<Sounds good>> About a year ago I purchased two Tiger Jawfish about two months apart. Initially they had a couple spats but got over themselves. After I moved and re-arranged the tank they started living with each other. Now the female stays plump and the male has a new batch of eggs in his mouth every couple of weeks. I have a brine shrimp tank where I hatch them but I haven't seen any baby jaws to feed. I use a turkey baster to feed my corals, I used that to spray some of the hatched brine shrimp into the Jawfish den. It's been about 3 months since it's started and I was hoping you had some advice about raising them. I'm moving in the next month so I don't have a lot of time. I doubt they'll start breeding again after I move. <<Your best bet to attempt to raise them is to move them to a separate aquarium as they will more than likely become a nice meal for other inhabitants>> I was also wondering what this coral is (only photo of just a coral attached) It's about the size of a volley ball and it seems happiest about a foot from the top of the tank. <<The coral is a Favites SP closed brain LPS coral. Looks bleached with a severe loss of colour. Please read more here http://www.wetwebmedia.com/faviidae2.htm >> If I need to list what's in my tank I can. I included a couple photos of where the Jawfish den is (just under the rose anemone) Thanks ahead of time! Matt <<Thanks for the questions. A Nixon>>
Coral ID 1/23/08 Greetings, I purchased an existing reef system a few months back from someone who was getting out of the hobby. The ID list of corals I got from the previous owner contained mostly common names and I need some additional help identifying a couple of them with scientific names beyond what I have found on your site and in Eric Borneman's book on Corals. <Good> Attached are three pictures of the corals in question. Picture one is what I believe is a Scolymia species that is about 4" across. <Agreed> However, I recently saw in your FAQ's a picture that looked very similar that was identified as a Cynarina. <Are hard to distinguish w/o close viewing of their skeletons> Can you confirm which you think it is? Picture two is what was described to me as a "Green Slimer". It is about 3" tall. Is this an Acropora species? <Yes... likely A. yongei, A. haimei... from Bali, elsewhere in Indonesia> Also, you will notice that one of the tips has at some point in the past broken off and is now attached in a horizontal orientation. Should this just be left as is or removed? <I'd leave> Picture three was described to me as a Sunset Montipora. <... I have seen this> It was originally growing in an upright branching form but now has taken on more of an encrusting form. My recollection from reading material on your site is that this is not unusual. <Correct> Based on picture is it your impression that it is in fact a Montipora species? <Is within this genus> Thanks for your help, Russell Furst <Welcome. Bob Fenner, who wishes SaraM had responded here... Will send to her folder>
