One of my two (bought two (had a bad experience with them in the past. I ordered a GREEN (!!!!) wildcaught Tetraodon miuris Congo Puffer and the damn thing died during transport... Which pissed me off because of not only how rare that color is, but for what I paid ($20) I could've easily ordered 2-4 and just sold the extras off eventually...)) fahakas puffer up when I netted them out of the bag to acclimate them to the higher pH. I would've ran and got a camera since it just looked soooo funny seeing a baby fahaka puffed up like a golfball, but he puffed up with air let alone being out of the water so I added them to the bucket with fresh warm dechlorinated tap water and he deflated immediately. I am not sure if that is the one I have now or if that is the one I sold to my LFS.studd muffin;4013760; said:when you try to net them do they puff up? and thank's for the info emartin!
But I've netted them tons of times since then for identification (when I had the two, one of them kept squeezing through the eggcrate divider to the other side giving the other a hard time) and relocation and never puffed up again.
They really only puff up when threatened or stress or in mortal danger.
I did see a video a while back of either a fahaka or a congo puffer puffing up after the live feeder crab grabbed and pinched the puffer's skin. I am not sure what happened next as the cameraman stopped filming and I assume ran over to help the puffer out by removing the crab...
Though sometimes they apparently puff up for no apparent reason! Here's a cool video of a porcupinefish (technically they AREN'T puffers but a very close cousin and obviously a member of the same group of animals) puffing up in a public display aquarium for no apparent reason:

I must point out though that you should not attempt to force your puffer to puff up... It can be very stressful on them (the crap about them dying after puffing or after 3 puffs is a load of crap, but it still is very stressful for them). Hopefully you'll see it puff up at least once...
I do here porcupinefish do puff up more regularly (as that video above shows) but I have no personal experience with them and they are also full marine fish anyway...
