It happened again, 85 fish dead.
Yes they're Tilapia, (a garbage fish) but this shouldn't be happening.

An equipment failure at the Calgary Zoo killed 85 fish in a pool they shared with hippos.
The failure of an ozone sensor has confounded zoo officials after they replaced the pool control system during post-flood repairs in the Savannah building in the Destination Africa area.
The malfunction killed nearly half of the pool’s population of tilapia earlier this week, with about 100 of the fish surviving the ordeal.
