Anyone have a good suggestions for a Royal Knife in a 75? I'm down for any suggestions but I'd prefer some fish that are a little out of the ordinary. Doesn't mean that they have to be rare and expensive, just not something lame and plain.
 
banjo catfish, they are not too terribly common and they add a cool look, plus mine is my BGK's best friend
 
Banjo cats arent active at all. Plus, a royal knife will outgrow a 75 quick. They grow so quickly, I've heard of crazy tales of a few inches a month. Why not do something that can actually stay in a 75?
 
^ Agreed. Mine grew from 2" to 15" in less than a year. That 75 wil be a very temporary home for that knife.

Also when it gets larger it will get very territorial. Mine was fine for around a year and a half with his tankmates, then one day snapped and killed everything. Only survivor was a Dojo Loach, and he was injured by the clown knife pretty seriously.

Id keep him alone until hes in a bigger more permanent tank. Or trade him for something thats more community friendly.
 
A royal knife will eventually outgrow a 75 gallon. However, with that being said if you are able to upgrade to a larger tank like a 125 or bigger then I would say do multiple types of knife fish or polypterus.
 
Yeah I had the chance to get a really big Delhz but they just look.....dirty when they're big. I mean, their coloring just gets mottled and dark. Ornates and Endlicheris are still pretty incredible looking at the larger sizes.
