How long would you treat?
I posted about this a while back....I have had a nasty parasite in my tank, that has been killing one fish at a time for months. The fish develop one or two pale or bloody spots on their bodies, with a tiny white thing sticking out of the middle.
I finally figured out that it must be a worm-ish parasite of some sort. It was not long enough to look like pictures of anchor worms I have seen, and for a while I wondered if it was really just a white pustule and not a parasite.
However, I did an amateur autopsy on the latest victim, and there is a perfect little hole in the middle of the spot--I am sure something is burrowing into or out of my fish.
Over the past few months I have treated with Jungle Parasite Cure, levamisole, and antibiotics, and still they were dying, one after another.
It is a slow process and only affects one fish at a time. It develops the spots with the white things, then lives for about a week after they appear. When the fish dies, its belly looks a little bit fat. Then within another week, a new fish will develop the same thing.
A few days ago I finally decided to try using Rid-Ich (formalin and malachite green). I looked at Coppersafe, but was worried about my BN pleco and corycats.
I have been treating with Rid-Ich at a half dose (found it recommended online, and had disastrous results when I treated at full dose years ago). So far the fish have had three days of it, with a 50 percent water change before each dose.
The instructions on the bottle say to treat for 3 days for ich. This is not ich, and anyway, am I not supposed to be worried about the life cycle? I am wondering if I should treat longer, given how persistent this nasty problem has been. Or should I give them a little rest between treatments? If so, how long? I realize I may be messing with my bio filter, so I will be changing water anyway. I want to keep medicating if it will help, but I also don't want to stress them out too much.
Any advice would be much appreciated. So far they are tolerating a half-dose just fine. Now I am even wondering if it is enough.
Thanks in advance for any comments.
On Edit: Ugh, I don't know if Rid-Ich is even going to work. It says on the bottle it kills protozoan parasites. I think I have a worm.
I treated with Jungle Parasite Cure for a long time and it did nothing. Levamisole didn't help.
I am at a loss.
