She is in the trap now, and she doesn't seem unhappy at all. In fact, she seems happy to get away from the bully of the tank, the other balloon Molly.
The bully is so crazy, she chases her around when they are both in the tank together, but when the gravid one is in the trap, well..look!
On another note, does she look like she is gonna give birth soon? And, when she does, will it be ok if the newborns are in the tank with the one-month-olds? If necessary, we can set up the net and put the newborns in it in the big tank until they are big enough.
