​***MAIN QUESTION***
I have 40Qt tubs with 3in heat tape installed in the back of the rack (short side). Is that enough for fully grown BPs or should I add another 3in section in front of the one already in there? This might sound like a silly question, but I'm going from glass tanks to plastic tubs.

*Secondary Question*
I plan on getting a few babies, would it be better to put them in a 20Qt tub instead of using the 40Qt I already have? I know it's more convenient for spacing issues, however that's currently not an issue for me.

Thanks for the help guys/gals, excited to be back!
