What's The Minimum Tank Size For A

[GobyMaster]

Hey, I have a 55 gallon tank that I will soon be setting up (to move my goby and bichir into), and I was wondering: could a black ghost knifefish be kept in a tank of that size?
Thanks,

The ideal size for a full grown adult would be over 150 gallons (5x2x2) but in my experience they are slow growing fish that rarely reach anywhere near their full 20" potential in captivity. As a bare minimum i would recomend a tank that is 48 inches long and 18 inches wide, height isnt as importent as they will spend the vast majority of their time on the bottom.
