As with all fish, you have to watch for your individual fish’s temperament. Even a so called peaceful fish can be aggressive; therefore it’s pretty much a hit or miss type thing. Even jardinis can be mixed into community aquariums but that doesn’t mean every jardinis will be compatible with the fish you plan on keeping. The comments were for general tank mates for gars, not every combo will work. Perhaps I should have said friendly catfish like Megalodoras.
