i have a standard 55 gal that i want to set up for my 28" red tailed boa. i also would have the 20 long that she is currently in. would it be possible to keep a tank inside of a tank? if so what about throwing a spare AC 30 filter on the 20 gal and setting it up inside the 55? i also have a 10 gal since the 20 seems like a tight fit... anyone ever try this? i had a 55 that i syliconed a divider on one time but i hated it and it was a real pain to remove... any input would be helpful (btw it is on a solid stand so im not worried about to much pressur isolated on one area)
