travisb15 Posted March 12, 2015 Share Posted March 12, 2015 I have hundreds of these little guys all over one of my LR. Not sure if they are good or bad. Also new to the forum i have restarted my saltwater hobbie with a 29g bio cube. Thanks. Link to comment
Evanski9 Posted March 12, 2015 Share Posted March 12, 2015 They are harmless, but they are ugly... toss it or trade it for a different rock Link to comment
CronicReefer Posted March 12, 2015 Share Posted March 12, 2015 I got a few colonies of those as well. Pretty harmless imo. Link to comment

The sting other corals and they reproduce very fast. Get rid of them fast. Link to comment
amphipod Posted March 14, 2015 Share Posted March 14, 2015 Hydroids are an extremely diverse group of creatures, not all hydroids are super quick growing, a few are extremely powerful, and fast reproducing, some have wicked powerful stings. Yet many of them are slower growing, and many are delicate, your hydroids bunched growth could be a sign for caution, how quickly are they growing. Link to comment
RK_tek Posted March 14, 2015 Share Posted March 14, 2015 I couldn't tell from the pictures, but make sure it's not Neomeris Annulata. It can take over the entire tank and the spores can lie dormant for several years. Ask me how I know. NM. Got on the Pc so I could see pics better and I can see the tentacles coming out the top. Neomeris just has a rounded top. It's a calcerous algae. Link to comment

I have them in my tank and they grow fast and spread like weeds! Link to comment
k427 Posted March 14, 2015 Share Posted March 14, 2015 Don't mean to hijack but is this what I have too? I assumed it was just some macro algae because it literally hasnt changed over the past six months. Thanks! Link to comment
RK_tek Posted March 15, 2015 Share Posted March 15, 2015 how do you know lol It took a tank crash, all new rock and fragging off anything that had neomeris on it to getrid of it. Every now and then ill see a stalk coming out of a coral that i movec from the old tank. Fire up the dremel with a diamond wheel and cut it off. Doesnt matter how much you like the piece, cut it up..

travisb15 Posted March 15, 2015 Author Share Posted March 15, 2015 they are not growing quick at all seems to have the same amount on it sense buying the LR. What kind of fish or invert would eat these?? thanks for all the responses! Link to comment

What kind of fish or invert would eat these?? thanks for all the responses! just let it go it's probably harmless, how many months has the rock been there? Don't mean to hijack but is this what I have too? I assumed it was just some macro algae because it literally hasnt changed over the past six months. Thanks! yours is algae or sponge, it's fine let it grow in peaceIt took a tank crash, all new rock and fragging off anything that had neomeris on it to getrid of it.

travisb15 Posted March 15, 2015 Author Share Posted March 15, 2015 havent had it more than two months. Im going to wait and see what kind of growth there is. Link to comment

Im going to wait and see what kind of growth there is. They are colonial hydroids and they start popping up all over the place just like aptisia. Actually, they are worse because nothing eats them. When I grab them with my tweezers, they are so strong that I can literally lift up the LR and I have to twist them off! Link to comment
amphipod Posted March 15, 2015 Share Posted March 15, 2015 havent had it more than two months. Im going to wait and see what kind of growth there is. good keep me posted if and how it changes over time, I've seen a case where someone had an unusual hydroid in his tank, he left it, and it made one bud and hasn't changed since lol Link to comment
ndrobey Posted March 15, 2015 Share Posted March 15, 2015 I'd toss the rock and get a new one. Link to comment
amphipod Posted March 17, 2015 Share Posted March 17, 2015 What is the fate of the hydroids? Link to comment
travisb15 Posted March 17, 2015 Author Share Posted March 17, 2015 good news so far they are not spreading... i think. The anenome has made a new home In the middle of the rock in question and is zapping a good amount of them to death and that is pleasing! I'd toss the rock and get a new one. This is a 60$ beautiful rock that i do not want to throw away if there is any hope of saving it. Thanks for the help anyway Here is the front where most hydos are you can see where the anenome has killed a Few on the left. Link to comment
ndrobey Posted March 17, 2015 Share Posted March 17, 2015 If you can get the anemone off easily, take the rock out and soak it in hydrogen peroxide. Then scrub it and rinse it well in ro/di water. Then put a generous amount of super glue all over the area where the hydos were. Link to comment
daydreamer Posted March 17, 2015 Share Posted March 17, 2015 I had a small patch that didn't multiply for months, but then spread to other rocks. Tried many things, but nothing was nearly as effective as a blowtorch to the infected areas. It caused die off but didn't kill the entire rock. Rinsed with saltwater in a bucket, placed it in another bucket of saltwater with a pump for a few days and then back in the tank. Link to comment
amphipod Posted March 18, 2015 Share Posted March 18, 2015 Obviously these hydroids weren't bad ones since bad ones have the legendary coral killer stings, your anemone ironically is worse than the hydroids If I were you I'd spare the hydroids this time around Link to comment
travisb15 Posted March 18, 2015 Author Share Posted March 18, 2015 amphipod i am leaning towards your opinion. If i see spread to other rocks or more on the same rock i will do either one of the ideas the last two said. As of now they are fine. More have died sense last photo the anenome is having a blast with them! Haha Link to comment
travisb15 Posted March 18, 2015 Author Share Posted March 18, 2015 I think this is a nudi but i am not sure. I do not want to pluck him out before i get a positive id. Can someone please help i have him and a smaller one that i am about to get rid of. Ps. Rocks are so white due to my soon to be former hungry hungry coraline eating urchin....

amphipod Posted March 18, 2015 Share Posted March 18, 2015 Nemertia worm, he is a scavenger of meat or a carnivore, some eat little crustaceans, worms, others eat snailand similar creatures, others eat eggs, very varied eating patterns You can isolate him and offer foods to see what he in particular likes to eat Link to comment
