Hey, so I was at a lfs and saw some cute puffers, they were green spotted and figure 8's. Please don't flame me, I just want to learn about them and ask a few noob questions. And no I did not buy them I'm doing research. So I understand there is a possibility that they will destroy everything put with them so I wanted to do a species tank. I found out it takes them a while to reach 6 inches and the ones at the lfs were only 1.5-2 inches. Would I be able to have one in a 10 gallon growout? And when would I start to increase the salinity? Also wat do u recomend that has personality and is just the coolest, figure 8 or GSP? 
please also help me get correct info, oh and I do understand what cycling is and that they need a cycled tank before you put them in. Thanks again!
