I've seen people sexing 1.5 inch slings, but it was with a microscope, if that answers your question. It really depends on the size of your t, it will be easier to sex as it gets bigger. I'm not a professional, but I would start at 2.5 to 3 inches for sexing. Jamie's tarantulas has a pretty good guide to spotting the spermatheca[URL unfurl="true"]https://www.jamiestarantulas.com/gender/[/URL]2.  Male and female tarantulas will look the same before they mature, and there is no way to sex most t's just by looking at their appearance before maturing. Males will look more gangly with long legs after their ultimate molt, with boxing gloves on their pedipalps and tibial hooks. 3. Sometimes the spermatheca is clear, sometimes not, it depends on the t. Let's say... like trying to see through foggy glass. It's easier to look on the other side. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />I suck at analogies</blockquote>
