I was just wondering if breeding blue tilapia as feeders in aquariums and closed system is ok. Since its counted as an exotic animal and considered as an invasive species ( it would also include all store bought cichlids as invasives). And of course your not suppose to release such fish in an open body of water. But as a Aquarium enthusiast breeding these fish for his Pet catfish and Bass, is there any problem in doing so, if they are kept in a closed system such as an aquarium?
