Freshwater versions of saltwater/brackish fish

  • We are currently upgrading MFK. thanks! -neo
Surprised no one brought this one up, but stingrays definitely fit.

IE: Xingu River stingray -> blue spotted stingray.
Didn’t even think of rays! Those would work perfectly!
Please read the last post of this thread because it may be a Freshwater specie according to the post.https://www.monsterfishkeepers.com/forums/threads/fresh-water-frog-angler-fish-info.712170/
Frog fish are great, nice that there is at least one freshwater/brackish one (though at that price it may be cheaper just to get a marine one lol).

I always thought that red zebra mbuna look a lot like anthias.
 
Antennarius biocellatus should be in brackish for long term...

I personally agree with you I had one in full saltwater. According to the last post the person states there are by location freshwater ones exist whether it's true or not I don't know.

If it's ever put up for sale, it's the perfect fish for the Jaws-loving fishkeeper that thinks bala, red tail, and roseline sharks just aren't looking enough like Jaws. Lol.

Dream setup is a black tip reef shark tank (cause you can’t keep a great white…)
