non-jumping fish?

well now that that is no longer an issue. does anybody have more ideas? after talking to a few friends on another forum i've decided to go with just one DP in the tank because they've had problems with their pairs being aggressive towards each other.
 
well, i've got the female DP in the tank and last week adopted a pair of t-bone(harlequin) rasboras and added 3 more, since one died i've got 4 of them in the tank for now.
