A reaction to an anti-parasite medication is being blamed for a die-off of the indoor fish collection at the Texas State Aquarium in Corpus Christi.
In a statement issued Wednesday, aquarium officials say the die-off happened late Tuesday night and early Wednesday. Aquarium staff members worked through the night to save as much of the collection as possible, but officials described the loss as "considerable."
The die-off affected the Islands of Steel, Flower Gardens and Lionfish exhibits. Unaffected were the Living Shores, Nearshore and Floating Phantoms exhibits, as well as outdoor and numerous smaller exhibits.
According to the statement, staff members had tested the treatment on a smaller exhibit previously without any adverse reaction. Aquarium spokesman Richard Glover says an investigation is underway to determine what caused the adverse reaction.
