I got the black plastic one with a opening in the side ( see one in the pictures of the pinstripe andrack post. )) I wish i had told my buddy to pick more up they nicer than using the plastic bowls. But I think he said the ones I got were like 8 bucks each. and with 23 snakesI need about 15 of the larger size and one super sized one ( about the size of a 60 quart tub ) for the boa.
