It's not necessary - that's for sure. But as I'm a beginer I think it helps me understand their growth and adjust feeding to their needs. It still up to you.I don't weight mine an there all perfectly healthy, it's just another job that I don't really fink is needed
That's a good point, my chams love to be handled (ok, love to be outside the cage ) so there's no extra stress for them when I weight them.If your Cham is not stressed with you, you might weigh it frequently especially if you are new to the 'business'. But if it is less social with you, I would pay more attention to the proper gut loading of the feeders (as handling it might be even more counterproductive then).
