I have a rack with 12 tanks, each tank with different fish. I think I’m getting an illness in one of my tanks and I’m concerned it will spread to all the tanks.
1. Should each tank have its own net?
2. Should I clean the nets before using on a different tank?
3. What’s the best way to clean a net?
4. I use a python for water changes. I can’t buy 12 pythons, so what’s the answer there?
Thanks!
