we had one of these guys (we just traded him in today). we accidently found out he would eat ghost shrimp when we bought them for our old brackish tank. our puffers wouldnt touch them but the BG would hunt them down. funny to watch him swimming around with the antenae still hanging out of his mouth. sometimes he would even carry them around by the atenae for a while before eating them. he lived in our converted salt water tank for a looong time but we recently added a ton of live rock and he couldnt find the shrimp before they died so we decided it was time he find a better home before he starved to death. but i totally agree with the picky eater thing, he never ate anything but live shrimp (he ate a dead ghost shrimp once) and we tried a LOT of foods. he was about 2" when we traded him in, he did grow a little but not much in the time we had him.
