man IMO I wouldn't. I have a greenspotted puffer FW, and though small he is one tough dude. Though no scales, they are well armored, and they actually have teeth (parrot teeth). They, like the cichlids are also pretty hot tempered.. and besides they'll prob pick the fights.. they love fin nipping. Also be wary of which puffer is poisonous, I know not all of them are but it would stink for you to loose two fish! Thats the funny thing about puffers... its a win win situation! But yeah I would say nay to the combo, but if you really feel adventurous, do some research on the puffers to see which is best tempered and which will cause the less damage to your fish or vice versa.
