I kept my centipedes in huge RUBS but my massive one managed to escape after being in it for about a year. Slipped out the gap at the sides. So I bought really tall plastic storage boxes. They where over 2ft tall so absolutely no chance of having an escapee. The foot print was no where near the same as the 145lt RUB it was in though and it was too small really. I sold my pedes before finding a proper replacement.
