Venom Fish?

Has anyone ever heard of these " venom" fish?   Where can i get them?

Splitfin flashlightfish I guess. They are saltwater

[Biotope Biologist]

They are saltwater fish that typically reside in the bathypelagic (deepwater) zones but will come to the coral reefs and surface to feed on various things. They do not typically do well in an aquarium and these will likely die. But I suppose they did their job on tik tok. 

 

A freshwater analogue might be the lampeye killifish. Although they do not bioluminesce they do have highly reflective blue eyes.

I should also say that some people have had mild success keeping flashlight fish but there are a few caveats:

-They are typically raised from babies

-The sacs under their eyes either never develop bioluminescence or it fades within months. 
 

-Still significantly reduced lifespan. Actually scientists used to think these fish only lived 1-3 years. Same with lanternfish species. But there have been some otoliths that mark them at the 10 year mark. Deep sea ecology is still wildly new and we know very little about how this all works. Lanternfish are caught en masse on fishing vessels. But rarely studied.

Another freshwater option would be midnight Rams.
