Good question. If I had the cajones to test it on some of my precious larvae, I would try the fenben, but...


I am still searching for an amphibian friendly method too, even though I am hydra free at the moment.

There appears to be some anecdotal evidence that Melafix wipes em out. I have had really good luck with it and various caudates in the past, but I am doubtful it kills anything but bacteria. I'll test this out after this weekend's fishing/herping/thankgodsthewinterhasended trip. If, that is, I happen to find some hydra in my bottom net scrapings.

I am compiling some interesting reading in this post related to this topic. I figure if enough of us brainstorm on this subject, we can come up with a solution eventually...;)

The pH adjustment method looks promising, however I am not knowledgeable on pH tolerances of most caudates (yet)

It also appears something called praziquantel has been used with success. Appears to have numerous trade names for both veterinary and human use...any one know anything about this one?

I have found it in an OTC for for aquariums here in the states, but dosing information appears to be anecdotal. I have sent off e-mails to all three manufactures to see what their "official" statement is. I have high hopes here, as Hikari is one of the suppliers and they seem to be very reputabale.

I know this post is old, but having run into a major hydra infestation myself, it popped up on a search I did. Just tried some Fenben today, guess I'll see how it works.

Meantime, I learned there is at least one drug free way to kill hydra, though it only works if the livestock can be removed for a few hours time. If that's possible, using water heated to 104 to 110 F for a couple of hours kills them all stone dead. My infestation came on a new plant, and when I realized how many there were ( green ones, they look a lot like bits of algae from a distance), I pulled the plants out and treated it in hot water. Worked very, very well, no trace of the hundreds of hydra remained afterward. They were a few different Aponogetons, including Madagascar lace.

Since I could not find a heater that would raise the temp that high, I put the plants in a bowl and started with water at 110F, and wrapped the bowl in a towel to retain the heat. I tested the temp periodically, and when it dropped below 104, I topped it up with more hotter water to bring it back up, no higher than 110 F. After a couple of hours, let it cool off to room temp and no trace of hydra.

This could be done for a tank, with plants, decor, etc. provided the livestock could be removed for the time necessary. I think I'd take the filter media out too, just in case it's too warm for the beneficial bacteria to tolerate.

    I've advertised my CB alpine newts for sale UK but no offers so far. I'm looking for a carer/enthusiast so I put a price to deter people who might not be serious about the responsibilities of the undertaking but how do I find a genuine enthusiast who will take over care? I'm not looking for money, just a good home for the newts.

    Hey guys, its way too hot where I live right now. Temperatures 40 degree celcius outside, making it like 30 degrees inside. Ive got ice packs on my yellow spotted salamanders hidey rock, he acts like he hates it though. Am I keeping him too cold? I think my temp gauge might be messed up, or at least in the wrong spot. I put the tank temp gauge in the top left corner of his large tank, where it says its 80 degrees fahrenheit, which I am aware is too hot, which is what makes me put the ice packs on his rock at the bottom of the cage, but the bottom of his cage feels a lot cooler tha 80 degrees. Should I move my temp gauge down to the bottom corner where he hangs out the most? Should I get a soil temperature probe so I can tell what temperature the soil that hes laying on is?

    Because his soil is certainly not 80 degrees fahrenheit, and I dont want to freeze the poor bugger with ice packs if he really doesnt need them. Hes been doing fine, but Im just so stressed because I cant get ANy information on how to handle this little guy. Theyre illegal to keep without a permit, but this one would not have survived without my intervention. So I cant call and ask anyone for help. If theres a betetr site than this one, I sure havent found it. But I never get any replies here. We are all just asking questions and getting none answered basically. Its really frustrating as I just want to help this little dude be happy and healthy. All I can get him to eat is potato bugs as well. I cant find anything else that he will eat. Is that even okay? :/ hes been eating strictly those since may first.

    I'm afraid this is the largest and most active community for this kind of information, probably on the entire internet. That said, we are still small overall. We can't help you all of the time. We do offer you support and have answered your questions in the past so I feel it's very impolite to lose patience with us.

    Third of all, assuming thats the case, no one seems to want to face the reality that these animals come from climates and microenvironments where they need to be kept cool. If you can't hack, then release it where you pulled it from.

    he was dying outside. SO SORRY i was nice enough to save him. can i even release him in wetaher thats 40 degree celcius? will he not just die outside because he cant dig through the hard ground?

    The ONLY reason I spent 500 dollars on this thing was to keep him alive. thats IT. He was completely dry with cracked skin and couldnt walk and I nursed him back to health. Now I should just throw him outside on the hard baked ground where I found him? in my driveway? Really dude?

    I am losing patienc ebecause I care. Because I cant get any answers in any length of time that will actually benefit him. He'll only eat potato bugs, I just want him to have good rest of his life. Thats IT. So dont act like I went out an dillegally trapped some poor salamander out of the wild for fun cuz I wanted one.

    I am very sure he was just trying to pass by, because he certainly cant dig ANYWHERE in the soil ANYWHERE near where I live. So I cannot just release him in 40 degree celcius on the super hard baked ground where theres no shelter and no food and now ater to be seen for miles. I dont see how that wioll help him at all.
