Thanks in advance. I am trying my hand at keeping a few Fairy Wrasse a McKoskers and a Yellow Back Fairy Wrasse. They are in a QT tank that's just a cycled tank. The Shop I deal with does a quick dip in Prazipro bath and keeps them in a system with Prazi and Copper Power. Is it a 100% guarantee that they need to be De Wormed ? If so with what ? What would be the proper course of threating? Should I automatically treat with Cupramine or Copper Power? What Therapeutic level? Should I Treat with PrazioPro? . (They are eating well Pellets and Mysis and swimming around fine No scratching). Or should I just let them be Chemical free and watch them close?. Please advise I'm new at this QT stuff.
