Yes I am the proud victim of MTS! LOL!
There is no cure I am happy to say!
Yes, I have a routine. I clean filters once a month and do 50% or more water changes once a week.
I test my water frequently and try not to overstock. If I do i can always start up another tank,
as I have 4 in storage.
I have been keeping goldfish for a long time. When I was 4 years old my mom and dad surprised me with 2 tiny goldfish in a bowl and that was it for me, I was hooked and I've never been without goldfish my whole life.
