In the lab I shortly worked at (albeit a different section) the " model organisms " - so Zebra fish - were kept in similar conditions. Cognitive research sometimes isn't necessarily done in better conditions and we are talking Germany here.
To be fair, while that's not great, they're lab animals and not being sold as pets (and lab animals is a whole different argument I haven't made up my own mind on).
