Sea spiders ?

Hi,

After trying to keep many corals and watching them turn white and die. I think I came across a picture that looks like the hundreds of things that are in my tank. Sea Spiders! 8 legs white (gray) in color with darker colored bands or rings on the legs. Does anyone have a good picture of them? I have a nice pink birdsnest which is not doing so good and there is tons on these things (spiders) on it! Should I remove and dip it. What would be the best dip solution to use? I know I have a tank full .. is there a tank treatment?

Thanks
Ed
 
there are 'sea spider' Eat/breed in Zoas as I recall. I seem to recall a thread around here somewhere on that.
 
I have them in my tank, a freshwater dip seems to get them to fall off....but so far my case has been a looing battle :(
 
allsps40 - I can imagine a scenario where it would naturally happen that a sps would be hit with a high volume of freshwater over some time.. and even the possibility of sitting in mainly freshwater waiting on a tide... Just because I can imagine it doesn't mean it really happens though. So I'm wondering what the dangers are of a freshwater dip.. I'm not suggesting it be done, just wondering the reasoning behind the NEVER just for my own knowledge.
 
Freshwater dipping SPS is fine, it's just like dipping Revive or CoralRx.
Not a drop of saltwater in any of those chemicals.
If anything, I figured the freshwater dip would be the safest dip.
 
I strongly disagree with a freshwater dip of SPS corals. It may depend upon the species and genus of course, but many Acropora species will be dead in a matter of seconds. In the natural environment some corals of course may be exposed at low tide and if it happens to rain, but these corals are adapted to that, and are usually not the corals we have in our tanks. Even in the natural environment the would not be 'dipped' into freshwater, ever.
 
Tested a few corals dipped in freshwater, no problems.

Not sure what the reason would be to dip them in freshwater.
Just wanted to make sure there wasn't a problem if it ever happened.

For example your water changes you forget to mix salt and instead you pour in fresh RODI water.

Just a thought.

that is just so wrong.
 
Well I can tell you that I rinsed a sps in fresh water to wash off some algae that I scrubbed off. The frag RTN'd quickly after. The dips for corals are ment to be mixed in salt water not to be used by itself. I cant think of any reefs in the ocean that see large amounts of fresh water. Even if it rains most corals are 15-50ft deep under water and the ocean is so large that some rain will not change the SG of the reef, at least no more than the SG will change in our tanks with a water change or adding top off. Also there are no reefs by rivers that empty into the ocean, there is to0 much waste and nutrients from the run off for corals to thrive. Reefs are super stable all year around and when something does go wrong there is normally major bleaching or die off on the reef. You can fresh water dip your corals if you like, but I would never do it again from my own experiences. Now I have fresh water dipped clams before to cure pinched mantel, 5-10 minutes and they are good. I even forgot a baby maxima for close to 30 mins once and it was fine. I always made sure the temp and ph of the fresh water was the same as my tank before dipping though. O Hand many people have had tank crashes from dumping in to much fresh water like an ATO malfunction.
 
Allsps- I was more envisioning tide pools.. and not necessarily rain, but water falls. Quite possible sps don't existing in those conditions. I appreciate the time you took to follow up. I appreciate the chance to learn from yours, and others, experiences.. but I guess I ALWAYS require an explanation.. :-)
 
ummm-
in mexico, near cancun there are many freshwater rivers that empty into the ocean.
there are lots of sps near these areas. i have seen sps growing on the edge of an underwater cenote that opens into the ocean ( a big hole in the ocean floor with COLD freshwater pouring out), and growing at the transition of freshwater rivers and ocean there- so i wouldn't say they are never exposed to freshwater. that being said, those sps are probably "used" to the freshwater they are exposed to, while i doubt the ones in our tanks are...

Well I use Revive and CoralRx and I can tell you there is an awful lot of drops of saltwater in my dips... Maybe it happens but I never actually heard of anyone actually dipping in undiluted solution (diluted with saltwater....)

It really just is not likely. Pollution from po4 and other waste from river run off is killing large reefs that are many miles from the river's mouth. SPS especially wild sps need super stable water quality, temp, sg and p04 level. So a sps growing right at the mouth of a fresh water river where the water clarity is very low, sg is low and there is way more nutrients in the water, I just dont see it as possible. Now a filter feeding non photosynthetic coral very likely.

The special on discovery I watched a few nights ago said that corals interbreed so much that basically "unless we sampled each one" we couldn't possibly know the extent of their genetic trees... They were at that point focusing mainly on acros and montis.. showing the diversity of each. So I at least somewhat disagree with "not likely". I do STRONGLY agree though that these aren't the corals that we're putting in our tanks though. (or the discovery special could be FOS.. but they tend to only speak in generally accepted theories, and don't report on "cutting egde" type science)
