Not that I can think of, My honest opinion is that this all started when i bought a raccoon butterfly. He was the first to go, i think whatever it was that fish had it and brought it into my system.
I always scoffed at the idea of quarantining fish for a while, if my LFS
does it before they sell me the fish why would I need to. Well needless to say i learned that lesson!
Am i going to have to do anything to my main tank? im going to give it a good cleaning since i have to re scape the whole thing. Just leaving it with no fish really will make whatever is in there die? Should i turn the system off for a while?
