debaser9 Posted January 15, 2006 Share Posted January 15, 2006 I'd appreciate any help identifying this guy. Only comes out at night and does not react quickly to having a light shined on him. It's tentacles are pretty much clear with whiteish balls on the end. The disc is about the size of a quarter, maybe a little bigger. Thanks. Link to comment
Bubble Posted January 15, 2006 Share Posted January 15, 2006 I have some that I think are a type of worm? does it retract into a small hole? or does it bunch up into a blob? because mine slowly retract into a small hole in the rock from light shining at night! if it blobs up than maybe hydrod of some kind? wow I shouldn't get so technical lol!

Caesar777 Posted January 16, 2006 Share Posted January 16, 2006 Does it have a skeleton? If so, then it's a cup coral of some kind. If it's completely squishy, then it's a Corynactis/pseudocorynactis anemone. Harmless. Not like Aiptasia in that it's not prolific and prone to stinging corals and moving around. Prefers dark places. Enjoy. Link to comment
debaser9 Posted January 16, 2006 Author Share Posted January 16, 2006 Thanks for the info. I'm going to have to do some closer investigation tonight to double-check, but I don't think it has a skeleton. During the day he just closes up into a tight blob. And it does look a lot like the corynactis/pseudocorynactis pics I googled. Glad to hear these guys shouldn't be trouble because last night I spotted about a half-dozen small ones on another of my rocks. Link to comment
debaser9 Posted January 26, 2006 Author Share Posted January 26, 2006 Just as an update/fyi for everyone, this ate my watchman goby last night. This is consistent with this article, which describes Pseudocorynactis as "not safe with fishes and adjacent invertebrates." http://www.advancedaquarist.com/issues/oct2002/invert.htm It comes out of the tank tonight.

oscar5453 Posted January 26, 2006 Share Posted January 26, 2006 Your Goby must of been the size of a nickle for that little thing to eat it. I kind of doubt it. Link to comment
debaser9 Posted January 26, 2006 Author Share Posted January 26, 2006 I woke up this morning to see the back half of the goby sticking out of it. I guess it's possible that the goby died some other way and drifted into the hitchhiker, but the goby looked great last night having his last meal so I don't think that's all that likely.

c est ma Posted January 26, 2006 Share Posted January 26, 2006 Holy crap! How big is your Pseudocorynactis?! Still the size of a quarter? (Great article--I had no idea they could reach 6" in diameter!) --Diane Link to comment
Joelle Posted January 27, 2006 Share Posted January 27, 2006 I have maybe 8-10 little Corynactis in my tank. Some are pink and some are clear. They have yet to do any harm. If you don't like it, I bet you can always use Joe's Juice? Link to comment
debaser9 Posted February 2, 2006 Author Share Posted February 2, 2006 I successfully (and very easily) got rid of these with Joe's Juice. Thanks for the recommendation. As for size, the biggest one (the goby eater) was not much bigger than a quarter diameter-wise. When fully extended it was probably 3" tall. Link to comment
formerly icyuodd/icyoud2 Posted February 3, 2006 Share Posted February 3, 2006 i keep them in my sump. and yes they are great hunters. it is possible it killed your goby. they are very very cool under antic lighting. mine are clear but under the blue lighting, vivid oranges and electric blues.
