I agree with above. With all that I have researched you need to do a proper quarantine t first and then do a proper maintenance of dt. So what I do is proper quarantine using copper, prazi and metro which would eradicate most of the common disease which could bring the display tank down. After that is done, I put them in display tank which has a UV steriliser and good water quality. Along with this, feed variety of food and add selcon once a day. This way, in case I mess up a little in the quarantine, I manage in the display tank.
