180G Stocking

[zagfuchs]

I have recently acquired a 180 gallon tank to upgrade from my old 75 gallon. I will be moving my current fish over, but being a bigger tank, I figure I might be able to put a few extra fish in the tank. I just wanted to see what you all thought about my ideas before I pull the trigger. Any suggestions or advice is appreciated, thanks in advance.
 
The fish i currently have - 2x Blood Parrots, 1x Red Spotted Turquoise Severum, 1x Banded Lepronis, 2x Catfish (I think they are Synodontis, but they swim upside down most of the time)
 
The fish I would like to add - 1x Albino Tiger Oscar, 1x Green Terror, 1x Royal Pleco, 1x Bichir or Fire Eel

Sorry, I couldn't figure out how to edit my original post, but I forgot to put in there that I wanted to get a few Silver Dollars to school in the tank. With the fish I have and the fish I want from above, how many SD's do you think I can put in there. I can't wait to hear back from everyone, I am very excited to get this tank going, but I need all my ducks in a row first.

I had a 150g tank years ago and kept similar fish. I had about 8 I think large silver dollars and they really did look amazing. I regretted selling them when I did to go in a different direction as they really are impressive as they get older.
I'd recomend fire eel as well especially more than a bichir. I had both but fire eels a better fish

My dad used to have SD's when he was a teenager and I have always wanted them since he told me about them. I was leaning toward the Fire Eel also, thanks, that helps a lot.
