i was looking at Wizkidzmom's old threads about using rain water and it said that her news did a report about misleading bottled water labels and that some are just tap water. i always give bottled water and i was recently at ginat eagle and got an 85 cent giant eagle brand gallon of water. do you think it is ok? will we have to start letting water sit? o yeah and i guess the girl with the 2 28 yea old hermit crabs lets thier water sit for 2 weeks! maybe that is why they are so old! maybe i will have the record for oldest goldfish mine is 8 years old almost 9!
