Well I called. The explanation:
"The pike in the tank likes to take a swipe here and there at the trout. That's what happens in nature so that's what happens in the tank to reflect nature and the local fish. That's how it is in the local rivers and lakes so we what to reflect the natural settings. So it's ok."
Hmm...natural settings have much more opportunities for the fish to escape as well as more natural and abundant features for fish to survive (cover, structure, etc.) and not to mention a tank IS NOT NATURAL. I didn't speak directly with the tank overseer but I did leave my name and number. I completely understand having a display if the fish are well taken care as well as their wellbeing but I fail to see the logic in comparing a tank with natural setting. It's like putting a cat in a room full of mice. Sure it's natural for the cat to catch the mice but is it fair for the mice? Eventually all the mice will be eaten. If they were in their natural settings I'm sure some if not most would get away. I'm a bit taken aback, this just does not sit well with me.
