quarantine tank question

[Baldy]

That's pretty much the stance I am taking on the issue. I personally I'll quarantine all fish before they go into the main tank. It might be a different story if I didn't have another tank to use. I won't go buy an all new setup just to quarantine in a 29 gal instead of a 10. This is just the decision I've made based on the wealth of information that I've read.

Daniella, do you treat all new fish hen you qt before you introduce them to the display tank, or do you use it only as needed?
