Well, some wierd things have been happening in this tank. After the first dose all looked fine, but then on day four (the directions say to dose, then wait four days and do a water change) I noticed the almost clear, stringy poops again. So, I did the water change and dosed again. This happened another time. It seems that every time they look good and then have a relapse. I am now down to only 3. Should I try another medication? Maybe a medicated food? I think that the parasite clear is pretty darn strong stuff (active ingredients are praziquantel, diflubenzuron, metronidazole, and acriflavine) which is why I am confused on what to do. I tried giving them bits of a mashed up pea to see if maybe they had just gotten constipated, and there was no change.
The thing that I don't like is that if I can't treat it the fish have a very slow death, which makes me sad even if they are not even feeder quality guppies. I also have plans for the tank that require the fish to move out, but they have to be healthy first.
I do think that I figured out the cause of the sudden deaths though. I was doing some reading and found out that if fish have parasites and are exposed to stress (tank move and even slow water parameters change in my case) their bodies can't handle the parasite loads and it gets out of control. So, I think that the parasites established themselves in the dirty water, and took over when the fish were stressed.
So does anyone with experience with internal parasites have any suggestions? Could it be something else entirely? If so why would the medication appear to work at first?
Oh, and just in case you're wondering why I have so many problems with diseases, it is due to this annoying habit of mine to rescue anything that I can. I have to say though, fish are a lot harder to help than horses or cats! :(
