Holy @&&^&*... sucks to see Mike, sorry for your lost.
No matter how well you care for your fish. Water could be pristine, chemistry on point, Murphy's Law always comes into effect. Believe it or not I enjoy the hobby much more now not having to worry about taking care of fish.
If at anytime I wish to see something nice I'll just go over a buddy's place and appreciate their collection. Not only do we loose the monetary value when stuff like this happens, but it's not like you can just walk into a LFS and re-stock?
