I ask this because this tank is not tall at all and I had 2 praecox rainbow, and 2 armano shrimp, one praecox rainbow and both armano shrimp jumped out and dried up.

I ordered 8 CPD and 20 manculent rasbora and I'm not sure if I should put it in the 60-F. I'm just afraid that they might jump out.

Are you able to cover the tank at all? If not with glass, with some sort of clear netting that won't be obstructive to the eye?

If not, you may want to consider going shrimp-only. They won't jump out unless there's a parameter issue or they're being hunted and have no place to hide.
