No. I am no expert in girafe catfish, but I know that they can reach 20" so 60g would definitely be out of the question. You can use it to grow out the catfish (like I think you are doing with the clown knife and aro in your signature), but expect to move all those fish including the aro and knife in a much larger tank within a year. Arowana would require imo at least 180g when adult size, knife more and girafe close to 180g too for a minimum...
Those are large fish, you need a proper tank to house them.
