I managed to luck out and the very first spider combo I purchased is an absolute trainwreck. It doesn't effect his quality of life, and besides being a charming little odd ball, he's totally fine. He sired my first clutch of eggs, eats pretty well (though I don't give him live, because his aim can be kind of off when he gets excited). Have a video of him "dancing" in his tub for reference. I adore this little weirdo!
Hope the video worked, haven't tried to post one before. Sorry if it doesn't work or if I'm not allowed to!
