I've message him as well, but no response from him too... sigh..

In another note, I'm having 2feet-by-1feet aquarium that I'm planning to use as the cage and planning to fill up the bottom 25% with saw dust/hay since they were reported to be a burrower.

Anyone know roughly how long would a 60L saw dust and/or 1kg hay would last in this setup?

Or is there better setup that can be recommended/suggested to me?

TQ
