Green spotted puffer questions

[Pufferpunk]

Buy clams, mussels, oysters, crab legs, squid & shrimp from the produce dept of your grocery store. Freeze & thaw when needed, in tank water with added vitamins. Remove all uneated food after about 10 minutes.

Hi I rescued three puffers from walmart two past away and I have one that is doing good I have had him for about a month and he is now in brackish water (they were in freshwater at first.)
So my questions...
How fast will he grow?
I have him eating brine shimp and ghost shimp should I give him anyhting different?
Is he a fish that will need to go in full salt at some point?
I have him with a few bumblebee gobys right now is he going to try to eat them at some point?
I have him in a thirty gal tank will it be large enough?
If I got a FW flounder or a dragon goby would either be ok for the tank he has?

i just did the same thing tonight man. just i got 1. the only heathy looking one that seemed to be there. i just couldnt let him be at walmart. well just thought id say that.
