Juvenile males

Its a huge 20 gallon tank, with 1 HUGE castle hide, and 2 smaller ones. all sorts of places to go... 2 water bowls, branches everywhere. I dont see them having any pro blems to be honest. but if i notice they do, ill yank em apart.

I got them for $10 each at this huge reptile convention..... so $20 lost isnt that big of a deal... if turns out they cant co-exist, ill just get a larger lizard or something and let him rule the tank...

The way I understand it the lumps are not the testies, but actually the hemipenes. I may be wrong, but that's what I've always heard.
