Hello everyone,

I just wanted to update everyone on the original thread I posted and also share my experience, as I think it’s pretty interesting and worth doing so.

First, I’d like to thank everyone who contributed to my thread and helped answer my questions. I really appreciate the insight and advice based on your experiences.

I initially posted on this forum to hear thoughts about possible cottonmouth and was quickly determined to be Ich.

The initial recommendations and advice were heavily focused around “medicating“ the fish and the tank. After reading a number of responses, and looking into the reasonings and chemicals suggested, I did eventually end up buying ParaGuard. ParaGuard seemed like the “gentle” medicating option and the least poisonous compared to the other traditional routes, although it was still contained the traditional poisonous compounds such as formaldehyde.

Continuing my investigation, I did come across quite a number of different “Natural” Aquarists and was introduced to the concept of treating the situation with heat and avoiding any poison. When I approached that idea here though it seems pretty aggressively met with skepticism. However after doing a lot of digging and research, I landed on a two headed approach and I removed what were visibly the sick fish, and left my main tank intact and in”medicated”. The sick fish were primarily the rainbow fish, as well as a blue ram, and those aware out in a 10G hospital tank that was treated with ParaGard over the last seven days. However, after removing what we’re visibly the sick fish, I still saw a couple white spots up here in the main tank, primarily on a pleco and that blue ram I mentioned before which was initially left in the main tank prior to moving it to the hospital. Upon discovery, I raised the temperature in my main tank to 87° and left it there for approximately six days. Simultaneously in the hospital tank I began treating with ParaGuard and also raised the temperature to 87°.

Currently as of writing this post, seven days after the initial steps were taken to address the situation, I have not had a single fish die and visually it appears that all of the fish are now healthy and free of any diseases in both the hospital and the main tank.

I make this post to say that while I do appreciate everyone’s feedback, I also want to note that there seems to be an inclination to pour toxic and dangerous chemicals into the aquarium to treat sick fish. And while I understand that inclination, the much more natural and non-poisonous approach seems to have treated my fish and I didn’t have to kill my plants or damage my hard earned nutrient-and-microorganism-rich substrate.

I’d love to discuss the pros and cons of more holistic approaches versus more pharmaceutical approaches to treating sick fish with the group. Both have their rightful place and serve their roles, but I’d love to discuss my experience with some of the other more experienced Aquarists on this forum for the sake of the discussion.

Again, thanks to everyone who took some time out to try and answer my questions and provided me options and how to address the situation. I hope everyone had a great week and I look forward to the continued discussions and being a part of this forum.

I am happy the Paraguard worked for you. Also, raising the temperature does not work on all parasites, and all fish cannot tolerate high heat either.

What temperatures kills parasites?

It is the best method to use a QT to treat so the medication does not affect the main tank if it does not need to be treated.

All hobbyists will tell you the best medicine is prevention.
 
Hi Chiguy,
I’m glad your fish are doing well.
I favour the heat approach for ich in tropical fish, and agree with your reasons.

To treat ich it is important to act quickly to treat the fish.
Equally as important is the need to treat for long enough. The parasite only has one of its life stages on the fish and can only be killed in the stage where it is free swimming looking for a host. The stage where it is encapsulated and on the substrate looks like it had gone, but it can then reinfect fish if treatment is stopped too soon. Treatment should be either for two full weeks, or for 1 week after the white spots have been removed from all fish.

Quick update for everyone:

The hospital tank fish have all returned home to the main tank. We did not suffer a single loss, and everyone is back home, cohabitating ich-free, with colors popping!

Just checking to make sure. Do you do know what the ich life cycle is and that it is possible for there to be a period when no fish appear to be infected and then suddenly they can be. "Medication" which can kill them in multiple stages are the most effective but also hard to find. Since heat speeds up their life cycle, it is the main reason for using it. lt is also why most meds direct that they be redosed over time even after the fish appear not to be infected. That ois because the Ich is in a stage where it is not evident and not able to be killed by the med.Most meds kill in the stage where the Ich is most vulnerable to chemical treatment. It is when it hatches out and seeks a host. Then it lacks protections.

Also, fish which have successfully fought of Ich develop an immunity against it, This is not a lifetime thing but rather a shorter term benefit, it isn't known how long it lasts on average. But the fact that it exists has spurred research into looking for a vaccine against it.

Finally. like many things in the microbial world, Ich comes in a variety of strains. This can mean some are more or less virulent and can different susceptabilities to any "chemical" treatment.

To be certain one has indeed beaten Ich, the fish need to be symptom free for a number of days. If you want a bit more in depth info, have a read here from the IFAS Extensiom of the Univ. Of Florida Ichthyophthirius multifiliis (White Spot) Infections in Fish
 
Glad to here all your fish are ok and are back home in there aquarium
