Goldfish basics
When acquiring new fishes:
- Get water ready before even buying the fish. As for new tanks, cycle them before purchasing any fish.
- Acclimatize them before unpacking @ home after purchase to prevent shock. 
- Once fish are acclimatized, place them into nice clean water with 0.3% salt. Preferably, do not medicate yet.....let them relax & get use to the new environment first overnight.
- The next day, observe carefully/thoroughly for any sign of sicknesses. Medicate according to the problems. Put bacterial infections first (JYP is my treatment of choice) to get them healthy enough before any further caustic medications for parasites or PP treatment....etc.
- Quarantine (QT) new fishes for a few days before putting them into the main tank with the others. Make sure fishes are active without any sign of sickness before putting them into the main tank. Do not feed during QT.
Hope these basics will be just a little guide for newbies. Pro-keepers....do feel free to add-in more details.
Thanks!!!
