SolidStylez: No offense, but really it sounds like you're in way over your head with this fish...
Puffers are great pets, but MBU's and Fahakas are not for the faint of heart... they need seriously large tanks and require very special care in order for them to thrive... and let me be honest in saying by keeping an MBU in a 10G is definitely not the way to go, especially since it sounds like your planning on keeping him in there for life, and hes already 8" long...
Honestly, i would say either sell him back to the store you bought him from, or give / sell it to a more experienced keeper who knows how to deal with such a fish... since feeding them pellets is going to get your puffer no where, they need shell fish in their diet such as mussels, scallops, clams, prawns etc for a well balanced diet...
So i would honestly say, unless your going to be setting up a tank at least 500G+ in size in the very near future, and ready to for the massive bills of feeding and keeping these fish long term i would return it now before it gets stunted or worst, suffers and dies...
