Cold Fish

The San Antonio Express-News is reporting that recent Texas cold snaps have not been good for the state's invasive fish. Thousands of tilapia and plecostomus catfish (but note confusion as to which species this is) have been found floating dead in portions of the San Antonio River since December of last year. The culprit is thought to be weather patterns that led to several stretches of temperatures in the 30's (F). The non-native tilapia and plecos, which are from Africa and South America, respectively, do not do well in cold water.
