Adult BGK or not?

  • We are currently upgrading MFK. thanks! -neo
For me, since I will get 2 250g tank. The first tank are for my Giant Gouramis and the other one for a knife fish. I really plan to put an electric eel, or aba aba or fahaka or african lungfish. I really like the aba aba or electric eel. For the bgk, It will be with my gg. So please help me decide.
 
please help decide
 
Between a BGK, Aba Aba, or Electric Eel...I'd stick with the BGK. The other 2 would be more of a one and only fish tank.
 
i see, the aba aba and electric eel are very tempting
