Tilapia raised in inland tanks or channels are considered safe for the environment, since their waste and disease is contained and not spread to the wild. However, tilapiines have acquired notoriety as being among the most serious invasive species in many subtropical and tropical parts of the world. For example, blue tilapia ("Oreochromis aureus") (itself commonly confused with another species often used in aquaculture, the Nile tilapia, "O. niloticus"), Mozambique tilapia ("O. mossambicus"), blackchin tilapia ("Sarotherodon melanotheron"), spotted tilapia ("Pelmatolapia mariae"), and redbelly tilapia ("Coptodon zillii") have all become established in the southern United States, particularly in Florida and Texas.
