Taylor - Don't feel bad...I've had so many times I made mistakes and I felt like a "bad fish mom" due to stress, being in a rush, or being my usual airheaded self... I can't even count...Animals can be frustrating even though we love them. It sounds silly to some, when I compare taking care of fish to taking care of a baby, but I can now really FEEL for new infant moms...The having to be uber careful, and making sure they eat, and making sure their little world is perfect & calm so they don't die.
Confession - I did a full water change on one's tank, then put him in it, then it struck me
5 minutes later..."OMG, I didn't put the PRIME water conditioner in!!!! AHHHHHH!!!"
Multitasking is a dangerous thing. lol. He was fine, but I felt soooo bad....
EDIT: And I moved one & he had fin damage even when I tried to be very careful. It sucks but it happens.
