Acclimation struggle with powder blue tang and yellow tang

[thincat]

When you say "except for the Sailfins" is this because of their size?

[Innovator]

Yes, they get fairly large and most standard 125g's don't facilitate their swimming movements well due to the width. If you HAD to purchase a sailfin, the Zebrasoma desjardinii can hold its own better than Z. veliferum. Just my opinion.

i had the same problem with my powder blue but all i did was cut the lights and cover the tank with dark sheets for 24 hrs. and every time the powder blue was ok after that and if you want a reall nice tang i have been looking in to a sohal tang but best of luck to u
