My dog faced puffer spits at me when he's hungry.
My bursa trigger tries to get in this hole in the rock and can't figure out why he cant fit and the niger can. he hasn't figured out that if he would go around back the hole is twice as big.
with the puffer you should stay away from lions.you might run into nipping problems. a trigger or two and maybe a snow flake eel.
But then this is just a ?noob? opinion
