The Texas State Aquarium in Corpus Christi announces a chemical company is to blame for the death of 389 of their fish.

The aquarium says they purchased parasite killer ‘trichlorfon’ from a company called Fishman Chemical. After testing the water, aquarium officials say the chemical was mislabeled, and the fish were poisoned with a toxic chemical. The owner of Fishman Chemical says they’ve never had a problem like this before, and is not admitting to anything until they conduct their own tests.
