BGK & Stingray....

I know one of the two species uses wave emissions(i believe it is the knife fish) and has the ability to change frequency as interference is detected. Would this not solve the problem?
 
Well I am in the univeristy library I guess I could start some research:P. It might take me a while though... (shouldn't I be writing a paper?) :)
 
From the above link
"The JAR has been found to be present in all species of fish that emit a weak EOD, mormyrids and gymnotiforms, except in the genus Sternopygus."

The bkg is of the genus Apteronotus...

JAR = jamming avoidance response

Just as a note, teacups are not a specific "species" of ray, it's just a generic name for any baby ray or "pup".

Actually that "used" to be the case until recently. Teacup rays are a relatively new stingray on the market and there hasn't been a lot of research until the last couple of years about them and now there is a classification of ray species known as a "teacup" meaning that it is a "miniature". Information on the teacup is still very scant as research continues but there are some sites that post what little there is.

Hope this helps ! :)
 
Probably not but bgk can be considered bottom dweller since if it swims around it is usually near the gravel,FW rays don't usually tolerate other bottom dwellers or worse,they will eat other bottom dwellers.
