Sorry bro, they will litterally pop a 75 gallon, they can get bigger than the tank, electric catfish should be kept alone i think,nif i where you i would do some more reaserch on fish you would want, for a 75 gallon youre pretty much limited to a fish max 14 inches, so find a fish you like. For a catfish you could do 1 or 2 pictus catfish, there really nice and cool
