Dealing with my first ever capillaria infestation. Yuck. Lost one fish, but think the other two will pull through. Tank is planted and has a lot of nooks and crannies, so getting these dead worms out of here is a bear, to say the least. I looked everywhere for the right approach and PraziPro was not it. After that failed, I went to levamisole which is really showing results.
Here is what I am doing
2ppm for 24 hours in total blackout followed by a close to 100% water change, then repeat weekly for 2 more doses. After each dose, there is a LOT of cleanup. Will let you know how it turns out. I am also feeding levamisole medicated flakes. Fortunately they are both still eating.
In my case 2ppm is 1 gram of Levamisole HCL (drench solution) dissolved in water to treat 120 gallons. A lot of stuff I read was dosing up to 13 ppm! Just go ahead and get a little scale if you don't already have one. They are cheap when you don't need them and priceless when you do. I think this is the one I have: https://smile.amazon.com/LuckyStone-Portable-Electronic-Weighing-Stainless/dp/B00LL0Z1LQ/ref=sr_1_49_sspa?crid=1EQ4B3WWSIIEE&keywords=pocket+scale+.01g&qid=1553451483&s=gateway&sprefix=pocket+scale%2Caps%2C170&sr=8-49-spons&psc=1
This adventure has also taught me that guaranteed snail free isn't a guarantee of a snail free tank. Killed one a month ago and two today. I also learned that levamisole doesn't faze them unless that is why they came out of hiding. Might have been the blackout, though.
And I carried 2 garter snakes out of the house this morning. One greeted me getting out of the shower and the other was hanging out around the RO barrel.
Yes drive back her to get fish, see the grand kids and hang out with your fish buddies.
Congratulations on being pest free! What a lot of work, but now you can rest easy. It's always a risk to bring new fish into the fish room even from excellent sources. So glad to hear that your tank has settled down. My barbs are continuing to brutalize the plants in the tank, even the ones they don't eat outright. They're just too intelligent and mischievous. They like to rip up the anubias from the zip ties holding the plants to the driftwood. Why? Just for fun. Anubias are too tough for them to eat. Little buggers. They even figured out that they could rip up Crinum bulbs and eat the roots. The leaves and bulbs are too bitter, and they won't eat those but the roots? This is what they do all day long when I'm not looking. Not a single care or thought for the hapless fishkeeper who spent all that time and money aquascaping so they'd have a beautiful tank, little ingrates.
Final report - the levamisole did an excellent job with no detriment to anything else in the tank. I moved the fish to a glass bottom quarantine so I could vacuum up the bugs they passed (cathether syringe is a god-send) while I continued to nuke the tank without possible hosts. After 4 weeks, I was able to return the fish to the main tank and continued to treat both water and their food for 2 weeks. No sign of the pests. Will let it go for another month before I bring home more fish, who as always, will go into quarantine. They will be treated just in case since it doesn't harm anyone. I have NEVER had this kind of trouble setting up a tank. Now if I could get Hans Peter to quit pulling up my dwarf chain swords to build his nest. Oh, and no sign of snails, either. Maybe I got them. Probably not, but I can be happy lying to myself for now. :-)
Why aren't snakes in Wisconsin hibernating right now? That's crazy.
I have found that Fenbendazole (another worm treatment) will kill pond snails pretty effectively after several doses, but won't faze MTS.
Snakes in the drain?
