Wizzy Posted July 29, 2012 Share Posted July 29, 2012 I have several hydroids on my zoanthid frag. The frag has two types of zoanthids. One of the species is being adversely affected (i.e. closed up and not opening). How do I kill the hydroids? Not my picture, but shows the hydroids I have. http://www.coralpedia.com/index.php?module...;g2_itemId=6194 Link to comment
altolamprologus Posted July 29, 2012 Share Posted July 29, 2012 That kind is no bueno Try removing them with tweezers? Sorry I can't be of more help Link to comment
MeepNand Posted July 29, 2012 Share Posted July 29, 2012 For seahorses, you use some kind of treatment that will kill all inverts, but I think you would not want to use that... Tweezers +1. Link to comment
Derbird Posted July 29, 2012 Share Posted July 29, 2012 A good quality dip should take care of the little buggers. Just talk to your LFS and they should be able to point you to a good one. I have heard that these spread quickly so I wouldn't wait too long either. A good rule of thumb is to dip anything you add to your tank, expecally zoa's. There are so many pests and horrible things that like to hitchhike on them. Then they never make it to your system in the first place Link to comment

I was thinking of Fenbendazole, but have no experience with it. Any good reading I can do on this subject or an easier dip I can perform? I was thinking FW dip, but I'm not sure. ----- My first attempt at helping them was to remove the zoanthids and rub the surface gently. Then I blasted them with a turkey baster in a separate container of tank water and discarded the water. I don't think that will solve the problem though. Link to comment

On the Fenbendazole a quick search on the Net brings up a lot of articles as long as you add for aquariums to the search they should give you the info you are looking for Link to comment
mattidallama Posted July 29, 2012 Share Posted July 29, 2012 I only use the liquid Fenbendazole in my Dwarf tanks i dip all my macros in a solution of 0.1ml of Fenbendazole to ten gallons of salt water and then rinse with fresh water after an hour of dipping. becareful cause Fenbendazole will kill almost all inverts and it binds to most things you house in it so if you dip then in a tub that tub will leech Fenbendazole so keep that in mind but it will nuke those hydroids. seahorse source sells Fenbendazole as well as most vet stores but seahorse source sells it will instructions on the bottle so its easier to use. And i Fenbendazole can stress or kill your zoas even if dipped properly its basicly a last resort for coral. Link to comment

Thank you for the help though Albert ----- So, I just rubbed the zoas some more and plucked a few hydroids off. Instead of 10 or so visibile hydroids I now have like 3. This really is unfortunate though, because my zoanthids still haven't opened. Any more help? Would a dip in Coral RX help? Should I try breaking off the rock around the zoas (the rock around them has a few hydroids)? Link to comment
Wizzy Posted July 29, 2012 Author Share Posted July 29, 2012 A few of my zoanthids are opening Hopefully, I can eliminate the Hydroids with manual removal. I am still open to tips however Link to comment

patback Posted July 31, 2012 Share Posted July 31, 2012 Why not frag the zoas off and throw the plug/ rubble out? I have some that look just like that, fortunately they haven't affected anything. They're in my zoa rock too. Link to comment

I have some that look just like that, fortunately they haven't affected anything. They're in my zoa rock too. I will probably frag some of the zoanthids off. The hydroids are scattered throughout the frag though, so removing parts of it would probably have no effect. Also, I'm sure the hydroids are already in my tank elsewhere so at this point I just need to make sure I can regulate their population. Link to comment

You can try getting a Blunt-End Sea Hare" (Dolabella auricularia) from your LFS and then trade it back in when all the Hydroids are gone. That seems to be a way that works for most who cannot remove them manually Link to comment

That seems to be a way that works for most who cannot remove them manually Funny thing is... I actually already own one of those seahares Lol. It's not in the same tank though (it used to be and it started knocking over all my corals). I had no idea they eat Hydroids and if I find that the hydroids migrate to other areas in my tank I will probably re-add him so he can eat them. I feel a lot more knowledgable now haha Thanks- Wizzy ----- EDIT- I wanted to add that I will be fragging my zoanthids as soon as I get a face mask. I already have Coral RX for dipping them in after and scissors and exacto knife w/multiple attachments. It should be fun, I've never fragged zoanthids seriously before and I have a few mini colonies I'm ready to cut up Link to comment

It should be fun, I've never fragged zoanthids seriously before and I have a few mini colonies I'm ready to cut up I've only ever seen a few reports of some sea hare eating hydroids and none of it was from any literature, only word-of-mouth. It may not actually be this species. The same applies to limpets reported to eat them. Anyway, from what I do know, some Trochus species do actually eat hydroids--I just haven't really seen any other than the usual "tiger" Trochus snails available and they never touched hydroids (or if they did, it was negligible). I'm sure there's also some obscure nudibranch species out there that may do the trick, too, but good luck with that. Link to comment

I would think that if you keep removing them you may eventually get them all although I cannot be sure Good luck though and I hope you do Albert Link to comment
