I totally agree with you regarding exaggerations....
50 lbs lizard? Geez, I'm not into monitors, just tegus, uros and beardies, plus a few others. Believe me, I am more into the health of the tegu/lizards, etc than their size/wt. aspect. With Ozzie's wt. one would think he drags his belly on the floor.......nope, only when he is spreading his scent looking for a mate. :0) I definitely know the breeder's site regarding 28 lbs..... To weigh my tegus, I will use 2-3 methods (each tegu the same method as not to confound the wts with error chances), depending on their age/size. Babies/juives will be place inside a proper size bowl on the digital person scale (so your fish scale may be more accurate). Thus weighing the bowl of course, then the tegu, inside the bowl, substracting the wt. of the bowl. etc. Typically my adults will be weighed while being held, thus substracting my weight (at time of weighing each time as not to allow for too much error in my fluctuations). Or I'll also use a smaller rubbermaid container using hte same process as mentioned above for the smaller ones.
I also enjoy seeing photos of "sandfire" bearded dragons who look so very close to "normals" for increased profits.....
The one thing with tegus, they are not based on cost per lb. LOL......
Take it easy and thanks for the terrific conversation!
