I know that under black lights some spider species glow. My friend was stupid and impulsive and he got a H. Minax (Thailand Black) for his girlfriend for her birthday becuase he wanted a glowing spider. Now they call it the "psycho" and it is a bit of a mess. I wonder if G. Pulchras (Brazilian Black) does glow, at least, it would be a better spider for her. Speaking of this, i am trying to convinve them to get rid of the minax and give it to someone who knows how to take care of and love him/her. Anyone possibly willing?
