Mixing puffers with small fish

[fish fry]

Hello,
I am wondering if it is possible to mix a Long-Spined Porcupinefish with small fish such as Blennies, Jawfish, Grammas, Clownfish, Dwarf Angels.
How much room would I need? I was thinking about a 6-foot tank, now I'm thinking possible a four foot tank. I'm worried that the puffer would be agressive towards something so small.
As long as there is enough rock will I have any problems?
Thanks
Fish Fry

I have said it before and say it again- At some point if it will fit in the Puffers mouth it will eat it. I have had a puffer eat a Falco Hawkfish without a second thought after being with it for a few months. I have had Puffers eat Butterfly fish and cleaner wrasses so if you want to feed your Puffer live food then it may work (but the live food will be the smaller fish).
