Greetings to All!
I'm surprised to see this thread come back alive after so long.
I thought for quite some time to decide weather or not to write. I know that many of you will not be happy with me but then I decided to share my experience in hopes that others will not make my same mistake.
The quinine treatment was successful.
My fishes were without ich for one month before I did something foolish. I had time before my scheduled vacation to sit and happily watch them, but as many of you know, certain events and temptations will always throw a wrench into one's progress.
I saw a gorgeous Achilles Tang that is 6 inches long and has been at my LFS for five weeks. This guy/gal was beautiful - fat, gorgeous coloring, active. I spoke with one of the employees at the LFS and thought that this will be a "good" time to try adding since I've got four weeks left before I go on vacation to quarantine him...I must admit that I was feeling very good and behaving very stupid at the time. I brought him home and did a pH and temperature matched fresh water dip lasting 7+ minutes and put him in with my tangs. Why? So I can see if they all get along -and they did. Four gorgeous tangs swimming in my little 55 gallon tank...Three days later, I still haven't seen the Achilles eat. Three days after that I saw ich in the Achilles. No problem I thought, I still have plenty of quinine sulfate. I dosed for 7 days and the ich continues.
I was able to take the Achilles back to the LFS where he is still alive an well today.
I did a 30 gallon water change on the 55 gallon HT after scrubbing down the glass and PVC condo. I treated with quinine sulfate for 10 days. During this whole time. There was NO ich on my tangs. One week before my departure date. I dipped every fish with seperate temp/pH matched fresh water for 5-10 minutes and released them back to my DT which was fallow for 5 weeks.
Three days after they were in the DT, I noticed ich on the Powder Blue Tang, I waited to make sure that it was what it appears to be then I called my friend at the LFS who offered something that would make your cringe like I did - Formalin.
I know that this ich may be resistant to the quinine as it did not work on the Achilles, but at the same time I don't really know. Four days till departure and remembering that the fishes were starting to show stress in the 55 gallon HT when they were in there - I took his advise.
I removed all but two of my corals as the rock they were on was too big to transport as there were only about 20 zoanthids on one and two leathers on the other - these went to the LFS for baby sitting. I took out all my macroalgae, snails, hermits that I can find and placed them in three different tanks in my house - no, you silly, not my other DTs, just empty tanks I had.
I dosed two 25 mL of formalin every other day x 2, day before I left, I dosed another 30 mL with a 40 gallon water change 20 hours later. My pet sitter dosed a 25 mL formalin three days later and my buddy from the LFS dosed two 30 mL treatments each four days apart.
Two and a half weeks later, I came home to find all my fishes alive and well, active, eating, looking good. To my surprise, the zoanthids and leathers were alive and open as if nothing had happened. The water parameters stayed "good" according to my buddy from the LFS throughout. The only problem was...can you guess? The ich is still on the tangs.
I did a forty gallon water change and dosed 40 mL of formalin into my DT at night. I learned that the trophonts are always released between the hours of 2 AM and 9 AM so I've always dosed my medicines at night as it is the ONLY time when ich is susceptable - when they are free swimming and looking for fishes to attack.
The next day, my water was cloudy with a yellowish tinge and the floor with several dead bristle worms around an inch in length, so I waited for the formalin to stay in there for 24 hours then I did a 40 gallon water change and another the next day. I thought it strange that no bristle worms were lost with all the previous treatments so maybe I had underdosed previously. On the third day, I did another 40 gallon water change and dosed 35 mL of formalin. This time I found larger dead bristle worms largest was 6 inches. I did another treatment three days later and the ich continued to be on the tangs. I believed that there were new trophonts hatching daily in my tank and spreading the treatment out every three days was not enough so I started dosing every 48 hours. Today will be the fifth treatment and I've increased the formalin to 37 mL. I notice the ich on the fish is decreasing in number, so I think I might be finally getting somewhere.
So here are some observations:
1. I should not let my excitement or emotions come in the way of good fish keeping.
2. All the fishes that I've had are alive and well.
3. My zoanthids and leather coral are alive and they do open - strange?
4. My powder blue tang is as fat as any that I saw in the Maldives. My Atlantic Blue Tang grew 2 inches while I was gone. This also is surprising to me.
Before some of you send me some pretty nasty replies, please remember, what ever it is that you want to say to me I've already said it to myself. So please share your thoughts but hold the negativities at bay.
I didn't have to post this but I want to try to encourage others not to make the same mistake that I've made.
If some of you are wondering why I did not do copper, it is because I didn't want to put them in that 55 gallon HT.
With this, I hope that all is going well with you and yours,
Best wishes,
Blennie
