Silver arrow tank idea?

[xWhiteyx]

Hello all i am just trying to figure out what i am going to put into my tank. It's 185 gallons this is the first idea

Silver Arrow ( u guys know how big they get)
3-4 Hujeta Gars (max size 8in)
ornate bichir (max pretty big like 24in)
and maybe a clown knife (max 3ft but have never seen them past 24in)
i also would like something more of a middle swimmer. but i don't know what

Second idea
Silver Arrow
2-3 Oscars
Ornate Bichir
clown knife
and thats it for this one

So what are you thoughts if you think you have a better idea let me know but i want a silver arrow for sure and an ornate bichir

Thanks for the help
