Feeding a saddle back puffer

[dazed1]

I just picked up the cutest saddle back valentini puffer yesterday.
After accimilation i fed it some frozen brine shrimp soaked in garlic. It ate it quite fast and almost all of it !
What food do they prefer ? Do they need any specific care ? I have two other 3 stripe damsel's along with him but they do not bother him or either way. I don't plan on keeping the Damsel's very long and will give them away.
Would it be possible for me to add one more of the puffer or would it be too much for my 20 Long ( after i take the damsel's out).

I fed mine krill. I also kept my saddle puffer with a valentin puffer this worked out fine for me they got along but in general its not recomended because puffer will usually nip at each other.
