At current size they will be good in a cylinder kitchen tub about 1 litre for depth or even 500ml would do just be more cautious when removing the lid each time. Want 2/3rds full with damp peat moss just make sure it stays damp right through to the bottom because funnelwebs are very moisture dependant and add some sphagnum moss on top to help retain it. 
Feeding on small crickets.
