They usually get over 1 metre so you would need a large click clack to keep it in that for its life. I have a pair of BHP's that are nearly a metre and they are in under bed storage boxes until they are bigger for there full time enclosures.
I have my bubba mac (think hes 7 months) in a 7 litre click clack and my 20 monthish mac in a 80 x 60 x 60 cm enclosure but i like to give them room. Im not a fan of click clacks/tubs as they get older
