You may have a tough time controlling nutrients in a tank that small since the eel has a big appetite. I've seen them in the wild in Philippines around 4 feet long, but I'm not sure how big they get in captivity if they are bought smaller as I've never actually seen one in captivity. Very cool animal, but personally I wouldn't put it in a 34-gallon tank. I don't think I'd even consider my own 69-gallon tank a permanent home for one. I think they are black when they are juveniles, aren't they? I'm not sure what size they would change to either yellow for female or blue for male.
