Blue Tang Question

[SleepyPirate]

I just purchased a blue tang last night at the LFS and its quite small mabey an inch IF that, its quite a bit smaller then my small clown fish.
Is there anything I need to know in the care for it and how fast do they generally grow?


I have a 90 gallon tank with:

50lbs Live rock
1 Lawnmore fish
2 clown fish
1 blue tang
2 Peppermint shrimp
1 feather duster
Med size colony of green star polyps
Med size candy cane
Small Blue Xenia
and
2 very large leather corals of some sort that are growing like crazy but never "bloom" cause of my inadequate lighting
