Paradise fish (IMAGE) Eötvös Loránd University Caption In Hungary, ethological research is most often identified with tests on dogs, but novel methodological advances could bring another species, the paradise fish, into the spotlight. Fish are easy to handle and produce numerous offspring, which could open up new possibilities for researchers in the fields of evolution and behavioural genetics. Researchers from ELTE Eötvös Loránd University have highlighted the importance of this old-new model animal in recent publications.
