No cycle on tank transfer?

[syncro]

New 35g tank has been up and running for 1 week with ammonia, nitrite, nitrate remaining at zero.

Is is safe to transfer the snails and crabs to the new tank?

The tank has had half a frozen shrimp to try and induce a cycle. The tank contains sand that had been sitting in a bucket for a month with saltwater, heater and aerator and several doses of MicroBacter. Also added a few piles of sand from the established 5g.
