yes i agree a 55gal fish tank is WAY too big . if you must use a fish tank get a 10gal or even 5gal .a bp this young with that much space will make him/her feel very insecure.or better yet go get a shoe box size rubbermaid tub .drill some holes ,a few at a time to adjust humitity till you get the proper hum.get a thermostat for a heat pad ,a couple shedspread tubs with a entrace .one one the warm side one on the cool side water dish .and your set till you need a bigger tub
