Advertisement I just got my first tarantula, well two now they gave me a free Mexican Red Rump aswell. I am so stoked about getting them, I cant really see the Red Rump hes so small so that'll be a pain in the butt to feed but for now I will ask some questions about my G.Rosea. I put a bottle cap with water in the enclosure about an hour ago when I got him home. He is already drinking out of it! (Or so I think. His head/body is over the cap). I think this means he was drinking out of it.. So my first question is, should the water I put in be tap water, bottled water, or boiled? My second question is when should I feed him/her? Should I wait a few days or what? Thanks!!
