the thing is 75 gallon is still way to small for a ghost knifefish. And a year is to long to house such a fish in a 50 gallon.in like a year or soo i am planning to upgrade to a 75 gallon or soo. i only have a 50 gallon right now because we live in a small house and thats all i can fit. i knew that the knife fish will get that big but it will tank time and until then i will upgrade anyway?
Please find a better home for the guy.
Either way with that fish in the tank you should not put anything else with it. Its not fun for the fish and for you to house it in a 50 gallon or 75 gallon. please rehome it. Sorry to say it but it is what it is. You did something on a wimp and it did not work out.Thats unlucky but sadly the truth
