Caught individuals have been identified, described and presented in photographs. Measurements of selected physicochemical parameters of water were made and perspectives for the studied population were evaluated. The finding is discussed with available literature describing introductions of alien species with aquaristical origin in Polish waters.

INTRODUCTION The fish kept in aquariums and home ponds are often introduced to new environment accidentaly or intentionaly by irresponsible owners. Some species of these ornamental animals are characterized by high expansiveness and tolerance to water pollution, which in the case of their release in a new area may result in local ichthyofauna biodiversity decline.
