Same, those are awesome.
But every fish I keep (bettas, hatchet fish, soon to be ropes/bichir) seem to have a knack for escaping fish tanks.
That would be no fun!
Years ago I had a pair of oscars that would escape their tank....ended up having to put brick on the top to keep them from jumping out. Even still..they got out one day while I was at work and died on the floor.
Was so paranoid about my marbles. I've heard stories that they love flying away while you're doing tank maintenance. Mine go chill at the bottom of the tank though, never seen anyone take off.
But, that one day, when the dogs knock the shelf or something startles them for real, they'd be gone without a lid.
