Well, not having a quarantine tank for the past 5-6 years has finally caught up with me. This morning I noticed Camallanus worms poking out of my largest Angelfish. Iv'e not seen any signs of it on any other fish, which doesn't surprise me because all my other fish were bought from online or my LFS. The larger angelfish I got from a store close by, but its iffy (Pet Store not an LFS), I took a silly risk, and I think that's where the issue has occurred from. I'm pretty gutted at this point, as i've only had ich once, and that was years back when I first started. Iv'e got some relatively expensive fish aswell now, so its really a big wake up call on how important quarantine tanks are. Anyway, iv'e just gone out and gotten Levamisole Hydrochloride a Pig and Poultry wormer, as from what i've read it's the only thing that works properly treating this. I've got the dosage rate and it's here ready to start dosing but there are a few things i'm still unsure about. My plan is to treat all my fish in the 75. I just need to move my L270 back over fro the 33 to to the 75, as he was in there a few weeks earlier so i'm assuming he will have it aswell. I'm going to remove all my plants and some hardscape and just toss it all in my 33 for now. So there will just be play sand, and couple pieces of driftwood for the plecos in the 75. I will treat the tank for 2-3 days, then on day 3 do a 80% water change, then another 80% a few hours later. Followed by the same process 2 weeks later. I have a few questions though. 1. Obviously, i'm concerned about BB. Will this Levamisole Hydrochloride kill most of my BB ? 2. Is it fine for me to take out plants and hardscape? Or do they need to be treated aswell ? It would be alot easier for me to keep it clean and observe my fish after taking it all out, as my tank is a complete jungle. But, i'm not sure if plants and hardscape would be infected buy Camallanus aswell ? If anyone has had experience with this and has any recommendations on what to do, please speak up, and thanks in advance. Im just wanting to hear others experiences before i start treatment. @CindiL I would really love to hear from you if you, if you have the time. You come across very knowledgeable about fish illness/disease.
