Releasing foreign fish in lakes caused lots of problems in the past, if the plecos survive and reproduce they can wipe out part of the lake's population in no time by competing for food. When a species is introduced into a new habitat it lacks natural controls on its population; predators, and competitors are absent and prey don't know how to avoid them. Without these natural controls, populations of introduced species often explode.
