Hey there kelsey. i have a four and a half foot
bredli in a dalbarb 4 foot by 7 foot high enclosure for him, he will right in that for life. I also purchased a hatchie that was born in jan 08 .(bought her a month ago) she is in the same tank as your looking at getting for yours. she is fine, apart from protecting her whole tank and gets me everytime i put my hand in shes fine. although if your ever planning on getting a stimson or anything small... DONT. i lost my stimy in the same tank, she went thru the click clack holes in the top. (everyone learns from there mistakes)
so yes the tank your looking at getting is good.. well your
bredli should be ok in there for around a year and a half two years i say
Cheers
Bec
