Warty newt and fire belly juveniles?

[Strand01]

I have a warty newt who lives in a 20 gallon long tank. I am looking to add some fire bellies. Hank(warty newt) is 5 inches long and the fire bellies would be juveniles. My question is would they all get along or should I set up a new tank for the young ones.
