He actually is just trying to bite me through the glass, but I can pretend it's love...
Lactoria cornuta *long-horned cowfish*
The risk of this fish exuding toxins is very remote, and the enjoyment is worth the risk. This fish, named Tweety (because he reminds me of a dead canary), will eat from my hand, spit water at me, and follows me like a puppy as I walk around the aquarium. He is a FUN fish, and the only one that really interacts with me.
I am positively, 100% not sure!
