If I had a fish that died because it jumped out the tank, I think I'd reconsider owning fish. Fish suicide that is!!
Oh snap! That's how one of my first fish died! :$ After that I learnt to keep a lid on the tank- some species have a reputation for jumping, especially ones that leap between puddles or rock pools in the wild, or jump to catch insect prey.
Thanks for doing the survey! You guys are awesome (up)
