150g Tang Stocking (First Tang tank)

[Potbellyrhino]

Heya folks,

Been reading tons recently and came across is good deal for a 150g.

So i've been going back and forth with my wife (She just wants a MBU puffer =X) and this is the tentative stocking list for our 5'x2'x2' 150g,

Please let me know if you see any glaring issues or have better suggestions!!

O. Ventralis 1m 3f
C.Leptosoma 18 (pref 3:5ish ratio)
A. Calvus Pair
L. Ocellatus 1m 4f
J. Transcriptus Pair
S. Lucipinnis x5

I guess my question is that looks like a lot of fish for most tang tanks i've seen =)
Is there an Omnivorous Featherfin that stays in the 5-6" range that pairs off?
I get that the Luci's and Calvus will eat most the fry and the Lucis will semi-annoy the Ocellatus but is that too much activity at the bottom?
Are the shellies just a step too far in the stocking? 2/3's of the tank is rockwork rest is PFS with some crushed coral stuff mixed in lightly. I like the sand and shell dwelling guys but dont have enough room with the rocks (i dont think) for the avg. xenotilapia or callochromis.So i left a corner open with some escargot shells.


Anyway , rambling aside, thanks for any input/feedback and suggestions!!!

Thanks

Jim
