Thanks I was thinking if an UTH was the way to go to move the central wooden brace on the stand and put a central heat pad to cover both sides at once so the cooler side is at each end plus once divided it would give each snake 24" x 13' x 12 "... The tank has two big drilled holes in the back where the previous owner was going to plumb in filters for fish... so I was thinking of fitting vents over each hole with silicon... but for $20 I wasnt gonna complain![]()
