So this might sound stupid to some people but I am going to ask anyway. So.... Last week I did a Salt water Fish rescue and besides the algae I am having no issues.
The same day i lost one of my barbs in my fresh water tank (55 gallons) thats 8 feet away. I didn't think anything of it. Well over the course of the week i lost almost every fresh water fish I had. My friend was helping me move the fresh water fish and I think cross used the nets. well long story short i had a horrific ich break out (first one that i had ever) in the fresh water tank and by the time i realized what it was most of my fresh water fish died... Like i said I have never had it before and it was miss diagnosed by help at the LFS
SO here is my questions
1) can I cross contaminate the tanks?
2) Is there something I can do that can prevent the ich in the salt water from taking hold?
I currently do not have any corals.
