The tank is in a quiet part of the house, also in the warmest. The pinkys are mouse pinkys (thats what the lady who sold her to us said to feed her.) If thats too small, what size do you think we should feed her? I also heard that feeding them 2 small pinkys is ok instead of one larger mouse. (which is what i was going to do) Is this not accurate? Thank you guys, youve made me feel much better!
