But the puffers take a long time to acclimate, and be sure to have a cave or overhang for it to sleep in at night. Oh, and don't let them touch the air, if they suck in any air they will die. They puff up with water, but only get a little roundish. Oh, and you must feed them snails, you can get them for free at any lfs. Just say, "I'll take any freshwater snails you have." And ta-da! A whole bag of little brown snails. The puffer eats snails that are about the size of its eye.
that covers puffers pretty well, just wanted to add something to it, if they do not get snails to eat their teeth will over grow and they will then be unable to eat eventually starving, also do not force them to puff it is not only stressfull for the puffer but doing it can lead to internal damage, it is a last ditch survival tecnique.
