I just want to say THANK YOU(s)! for all the help.
After a newbie mistake of putting 2 uro's together without knowing anything, I've managed to work things out. I got my Mali checked (he was the new addition), and he tested clean. I kept him separate since April, after being told to remove him incase of introducing possible parasites. I was really concerned, and completely sterilized both cages as a precaution, because I was afraid of losing my female Orange Benti.
The Mali (Rex) was checked again this week, and is clean, so they've been put together.
Once again, thank yous! I've learned now to quarantine all new animals before introducing them to another. I am just relieved that everything worked out in the end, and its because of the great people at this site 
Here's a picture of the pair happily basking together.
