Do bettas have teeth?! I've only seen mine yawn so I haven't been able to see... lol!
Yes they do. Except normally the fish is not monstrously huge like my female (unless they are giants, which she is not), and you would have trouble seeing them without some sort of magnification. Remember, these are carnivorous, predatory fish and teeth can mean the difference between dinner and a mouth full of water.
Lol, my sorority girls attack my hands XD they try to eat it... :O
LOL My sorority girls do that too! One time when I was putting in a new decoration, one of the females bit me and it actually hurt like getting a shot with a needle! But any other time their nibbles never hurt.
I love to play tag with Perry! I always start out as "it" so then I touch Perry softly and she turns around and puts her mouth on my finger; she never bites me. We do that until Perry looks tired and worn-out.
