that, you'll find that the fish is a substrate sifter and not a
piscivore. Of course, that doesn't mean that cardinals can't be

food. Are you sure you didn't just have a cardinal die somewhere in
your tank? Or are there other fish big enough to eat cardinals


I am familiar with both scientific names however you will note: "A.
flavus is probably the most popular of the amphidromous gobies within
the aquarium hobby. Aquarists frequently identify them as A. strigatus
or A. badius, however these names are synonyms of A. flavus." Flavus
isn't any more correct than Strigatus, they are the same species. Since
Strigatus seems to be more common in the aquarium trade I used it,
thinking that more people would recognize it than Flavus. If you would
like to nitpick please do it on your own time and don't involve me.

And yes I'm sure, I wouldn't have said it if I wasn't. I watched the
goby swallow the cardinal. The reference to it being his natural diet
was a joke. I doubt a goby could even catch a cardinal in the wild -
these gobys are not exceptional swimmers, they can lunge short
distances but that's about it. The only time he is going to catch any
prey at all is when it's on the bottom and comes too close.
