Message: <blockquote data-quote="testdasi" data-source="post: 175303" data-attributes="member: 32655">Just to make it more reassuring, I have experimented with Lasiodora parahybana of various sizes and found out that feeding a prey about the same size as the abdomen per day has no negative impact.The T's just grew faster and would stop eating if it was too full (i.e. not pre-moult related).Risk of falling injury is obviously higher with a big abdomen but that is easily mitigated.There was a hypothesis that big abdomen may cause rare abrasive worn on the bottom side of the abdomen, which is supposedly so heavy that the T can't raise it up and drags it on the substrate.While it seems logical, I have not seen it happening at all in my experiment and all the subsequent tarantulas that I feed with the "let the tarantula decide" regime. And I use pure coco fibre, which is on the more abrasive end of substrate so if anyone would see it, that should be me.</blockquote>
