I would j
I would just observe in QT. No copper. Treat with prazi. If they look good at 4-6 weeks, in the DT they go. I can't remember when I last used copper. Though, if I buy from my lfs they stay at the store for a month then go in my observation tank for a month.I may have taken water over my head here but i just bought 2 juvenile M. bipartitus that have been at the lfs for about two weeks. They are eating well and are active.
Now im wondering how to quarantine? I don’t have access to copper so my alternatives are essentially either tank transfer or molly qt. Thoughts?
