I offered sound advice, what I think most would consider constructive criticism. It's almost impossible not be to critical, when so much info is lacking in your threads. Thus far you are the only person that even knows what species of loaches you are referring to, as though all loaches are the same. LOL
You just got your GT turned around, and now you want to risk adding more fish? Like I said, good luck with that. FYI ...... unless you are sleeping with the person supplying the new fish, it's always a good idea to QT new arrivals. Some fish can simply be carriers, without ever showing symptoms, and when exposed (under stress) to new fish with zero immunity to that pathogen, oops, take a guess what happens. Again, just good advice from someone who has learned a lot of these things the hard way over the years.
Even if you ignore everything that I have posted, hopefully someone else will one day read this and pause and consider why I gave the advice that I did, and possibly reconsider a potential bad decision.
Good luck
