GBR plus paradise fish

[alLexX]

so,ive been looking for another fish/school of small fish for my 20. there is currently 1 paradise fish,5(gonna be 6) cherry barbs,and 2(gonna be 3) yoyo loaches. as you can tell,im worried the paradise fish will be a problem. hes not aggressive(i had to move the swordtail because she was picking on him...),so that shouldnt be a problem,but im still worried it wont work out
