No doubt! I think you made smart move by removing both and then starting over with all small tangs and CBB at one time.Not a surprise as I knew when I got the Yellow and PBT they'd eventually need to move onto larger systems. The Yellow could probably stick around another year here but if Im going to upset the balance I figure it best to do in one shot rather than multiple times. I also doubt the Yellow wouldever accept the Copperband.
Pyroferus is also a favorite of mine so far as Tangs go. Im a wrasse guy like you but the Tangs bring a little diversity into the tank. Pyroferus dont all turn into stunners but the ones that do can be amazing!
Yeah I am in the middle of upgrade and am planning more wrasse of course but am also thinking about other tangs to add to my juvenile Blonde Naso.
