Hahaha Jason,

Sometimes transfering a ladden female into a new environment will cause what I termed "stress induced spawning". If the fries are not mature enough most will not survive or worst still all dead because underdeveloped/premature.

The females will definitely stressed when you house them in a basket/new environment but this will not be very fatal. Maybe another sign you can looked for is prior to spawning, females tend to isolate themselves from the group, staying still at a corner or laying down. All these signals that it is about time. If they are still swimming happily then maybe is not time yet.

Normally the ripe female will spawn within a day after being transfered into a new environment. If by end of second day they still haven't drop then return them to their tanks.
