Fish getting along in QT

[Bigroost]

I want to add the next 3 fish to my tank. I would have to qt them in a 20L. The 3 fish are a yellow tang, purple firefish, and a yellow watchman goby. Is that too much at once or should these fish be able to make it for a month in tight quarters?

20L = approx 5 gallons. you should have a bigger QT. at least 10 for the gobies, and at the very least 29 for the tang. what size is your tank? if you had to put a fish in the 5 gallon, out the YWG in.
