I should think so their pretty small and the tanks pretty big just make sure you put a lot of sand aleast an inch and 1/2 to 2 inchs(hopefullyyou already new that) I would put to many rocks in there or you might not see them.
If you can you should realy put them in an realy tiny tank Tempraly so the pair up togther then you'll get symbiotic relation like what you have with the other pair.
