I've had him for about a week. He's about 9 in. long and is in a tank with a clown knife that is only about 6-7 in. So far they get along just fine. But...I recently got the ck off live food and on frozen blood worms. I bought the blood worms that are frozen into little squares and usually cut one in half and feed them twice a day. The thing I'm wondering about is....first...is this enough food? They seem to gobble it all up pretty quickly. And....second...the ck easily gets to that food first so I wonder is the eel is getting enough to eat. BTW....neither seem to be very interested in shrimp but maybe I'll put some in there to see if the eel comes around because the ck won't touch it. Thoughts?
