I just impulse bought a zig zag eel and a black ghost knife fish I put them in a 60 with my blood parrot gold sevrum and striped Rafael I have kept eels before when I was younger i kept a huge fire eel in a ten gallon and it lived a long time I know I am a terrible person for doing but I fed it live worms and that's the only thing it ate I heard from the store that they will eat blood worms any recommendations
