I'm not sure if I have them, but this is a pic I found off of Google. I can't get my camera to focus on them. They just started appearing on the glass about 2 weeks ago. They are clear/white anemone jellyfish starfish, looking LOL. And the only reason I said Hydroids is because a couple other people said that's what they thought they were. I'm just needing more opinions. Since I just came out of my cycle, there is not much in the tank. 1. I'm assuming I got them from someone... 2. If they are hydroids, how do I get rid of them? Is there anything that eats them? A few people mentioned about manually removing them. And when I say there is a lot, I'm telling you there is literally a 100,000 or more of these things. I counted over 300 of them in a 6 inch by 6 inch piece of glass on the front. I wipe the glass and within 30 minutes they are back. This is what they look like. Most have 4-6 legs. http://s118.photobucket.com/user/love2skiutah/media/IMG_0162.jpg.html" rel="nofollow">

I hope that they are completely wrong... At first I thought they were just pods cause they were so tiny, but they've grown into starfish looking tentacle things. And maybe I'm over reacting and they are pods.

Looks like pods in that picture. Here is a more detailed picture of them. They are a pain. I have heard stories of some success using "Blunt-End Sea Hare" (Dolabella Auricularia) as well as a very unlikely option of panacur(horse dewormer). I have never tried either of these but found lots of info about using both while researching it a year or so back trying to help a friend. I really hope they are just pods but that picture has me scared. Try taking a picture of them through a magnifying glass if you don't have a macro lense. ------------- My ocean. 90g (yup, won it!), 40g, 28g, & 10g Systems PADI Advanced Open Water http://utahreefs.com/forum/forum_posts.asp?TID=63568&title=krazies-nano-paradise" rel="nofollow - Tank Thread: |

Those are not "pods" and I have never known them to be a problem. This is not hearsay, but my own experience with setting up many dozens of my own tanks. These show up in new tanks and usually disappear within a month or so after they appear. Here is a close up from one of my new tanks. I suspect they do well at first because of the early hatch of Copepods (a variety of which are seen near the hydroid in this pic) or some other early tank resident that dies back leaving these to die off too.

Seems I have Hydroids to but not the free swimming species but in colonies. As Kraze4acans said in my research as well the only thing that ate them was the blunt end sea hair. I'm not sure if it is reef safe though because I decided to try to manually remove them. And the horse dewormer to kill them off, but as he said is a very unlikely option and I would definitely do more research on the effects it could have on all your other tank friends. Sorry to hear you have these guys in your tank such a pain I feel ya though. Keep us updated ------------- Creating my own ocean |

They are totally fine. In fact I'd like to have them in my tank. I've seen a problem with them before. Adam ------------- Come to a meeting, they�re fun! |

I think in small numbers they are not a problem but when the numbers get high they can cause damage to corals. Aaron your numbers are a little high but with it being early in the life of the tank you might not ever see a problem. You tend to run a ULNS and that does effect there ability to thrive. Once your system is running and your filtration is tuned you may not ever see them again. ------------- My ocean. 90g (yup, won it!), 40g, 28g, & 10g Systems PADI Advanced Open Water http://utahreefs.com/forum/forum_posts.asp?TID=63568&title=krazies-nano-paradise" rel="nofollow - Tank Thread: |

There are more than one type. Some appear to be pretty stationary and grow in clusters. Pretty easy to deal with because they grow in the same area. The other type are mobile and move around (this sounds like the type Aaron has) the mobile ones seam to be the bad ones that cause problems. ------------- My ocean. 90g (yup, won it!), 40g, 28g, & 10g Systems PADI Advanced Open Water http://utahreefs.com/forum/forum_posts.asp?TID=63568&title=krazies-nano-paradise" rel="nofollow - Tank Thread: |

Yeah, I'm getting a lot of mixed feed back on them. I posted in several other forums and half the people said leave them, they will go away and half the people basically said good luck lol

They are Staurocladia oahuensis (hydroids) and are common in most reef aquariums (I've had them in various tanks over the years...amazingly my current tanks are the only ones I've never seen them in.) Their population will wax and wane (like most other critters) with the nutrient levels. Usually aquarists will see a population boom for a couple months...then rarely see them again. In a reef tank, they're usually not a problem (other species of hydroids cause problems to coral...these usually don't). However, they can be bad news to fish fry and seahorse tanks. If I remember correctly, Panacur is used to treat them, but it's pretty nasty stuff on inverts. Long story short - I wouldn't worry. Enjoy them as part of your tank diversity. ------------- www.reefdup.com Diving since 2009, reefkeeping since 2007, & fishkeeping since 1987 200g, 75g, & 15g Systems PADI Advanced Open Water |

A few of us here will remember that in my first tank I had a small infestation of Hydroids. I found them to be a cool addition to my tank and were not harmful at all. Eventually they just disappeared. But I had a good colony of them at one time. This picture was back in 2005, it just seems like the other day. Mark and Adam and Jake should remember them.  ------------- 335G Reef TOTM. http://www.advancedaquarist.com/2015/2/aquarium ReefKeepers TOTM Feb. 2012 http://reefkeeping.com/joomla/index....k-of-the-month & |
