Is It rare? Whats it worth$$? can I keep more them one together?

I think it is difficult to say only looking by the internet! You are looking to the fish everyday, so you may say the exactly color!! Gymnotus has a lot of species with different color patterns!!
any way, it is a nice fish!!

 

[mudskipper]

but what about the questions. I am very eager to know

 

[drdpc]

probably in the USA it is very difficult to get one!! Here in Brazil it is very common, it is sold as life bait to fishery at about 1 dollar, and in aquarium store at about 5 dollars!
I use to keep them together and with a black gost knife also, without problems!!

Gymnotus carapo is the most common species of Gymnotus, not a rare species even when it's difficult to obtain. My 0.02

Best regards.

Daniel.
