what are you doing recomending a flavirufus as a FIRST monitor? since you asked tho...a friend of mine breeds argus (Camb PM me and I can give you his contact info) although not flavirufus, he knows on the species and we have spoken about them. flavirufus are a small to medium size monitor that require room to burrow as they burrow to escape the heat of the day. Also, goodluck at finding one for under $150.
Yes you have to know when to say enough is enough when feeding savs because they will eat you out of the house....the flavirufus also requires a lot of food for how active they are. They like the argus, will also eat you out of the house if you are familiar with Argus.
He has listed in his signature, a cornsnake, Ball Python, Leo Gecko, Argentina BW tegu, and a RES....
....why would you recommend a flavirufus? I would personally direct him towards an acantharus before an flavirufus for someone who is looking to get into monitors...
...Camb said he was researching the animals above, I am sure he will choose what suits him best.
