When you thing of predators you think of lions, tigers.
Sharks.
Why not think of frogs? My pet bullfrogs, Peanut and Olive, cant be more than two inches long!
But i love to watch them eat. I fed Peanut a spider today. He sat in one place, then lunged forward,
blinked twice, and swallowed. Just like that. If i had blinked i would of seriously missed the whole thing!
Some people think frogs are gross. Some people are dumb.
I personally think frogs are fabulous pets, but i guess if you don't like bugs, you may have trouble dealing with their diet. I love their personality's. Peanut is a ferocious hunter, and always likes to stay near the water, Olive however is a bit strange. She acts like a tree frog even though i saw her as a five inch long bullfrog tadpole. She even looks like a tree frog, and her favorite place in the tank is a mossy tree-ish perch.
Anyway, she is a bit more mellow than Peanut and isn't as freaked out when i put my hand in the tank.
 Oh, speaking of frogs, one of my other tadpoles turned into one. I am going to be over run with frogs!!!
My parents don't mind me keeping frogs, but breeding crickets may be a tad much.
