I have a related question. I had a tank do a near-crash--managed to get all the fish out. I have two discus temporarily in a 20L, and have a 55 gal. that currently holds three small angels, one large, and two male rams. Can I temporarily--day or two--put the discus (about 3-4 in.) in with the angels until I can get their tank up and running again?
thanks...Oh, about QT-- the angels have been in this tank for two weeks now since the auction. I've had the two rams in with them since Thursday, and previously they had only danios in with them. Maybe I shouldn't risk it?

thanks!
Yvonne
