So I guess I need to buy a tank that will hold them for a few weeks? Does that tank also need to be cycled prior to adding the quarantine fish? Basically having two tanks.
Yes with a quarantine tank you will need to maintain two tanks... I have a 30 gallon that is my main tank. I also have a 10 gallon running which I use to hold any new fish. I also use it as a hospital should any fish from my 30 gallon get sick.
What if there's live plants in the tank I think I have the same problem and wanna fallow the same prosedure they are new plants also I add a bit of salt to my tank on water changes.
