1st... most fish are afraid of fire!......Or that they will jump out of your reef, grow legs, and eat your family and burn your house down.
This is a good idea... I don't have a frag tank... maybe if I do go dwarf angel I'll get a frag of something from my DT and leave it in the QT after the angel is eating and happy and see what happens...
I take it you've had success with dwarf angels in reefs then Albano?
frag tank is good 'test' area, and it's easy to catch the fish, if necessary...
I have 4 dwarfs and 6 full size angels in my reef...most well over 2 years without problems...tank is VERY well fed!
