I'm not sure what type of fruit flies just that they are flightless.

The tank temp is down to 74, humidity is up to 85.

The tank is 12x12x18. I was orginally going to keep them in the 12 sq tank, but they were jumping so high that they were bouncing off the top. The pet store said they would be fine in the smaller tank together. They seem like climbing all over the tank and are quite active.
