Fish apocalypse aftermath
So, I fishless cycled my first tank in years, a 125. I decided to use some practice stock while saving up some cash for a full stock of Victorians. I used feeder "rosy minnows", a few goldfish, 2 plecos, ect. All have been pretty healthy and happy for about 6 weeks. I decided to introduce two silver tip sharkcats and within 48 hours all were stricken with some sort of fast acting illness and every last fish died.
I have gotten plenty of sound advice from another forum of what could have happened and what to do. completely tear down, bleach, scrub everything and completely start my cycle again from scratch, no problem.
Here's my question. Is it necessary to trash all of my organics? I have had more than one person tell me that all the plant life should be trashed. I have spent almost 6 months collecting enough java moss to construct a 6 ft long, 20 inch moss wall background. It is all installed and just started to creep out of the mesh. Enough said about why I don't want to chunk it unless absolutely necessary.
I also got some experienced advice to leave the tank fishless for a few weeks and any trace of disease or bacteria would vanish due to lack of a host and then try a few tetras and watch and observe, saving the moss wall.
Opinions? Learned lesson of importance of quarantine and I will raise the standard on my practice fish.
