Tons of new stuff, need fish ID please :D

[Wight]

Yesterday I got a huge amount of fish, a few 20 g tanks, a 50 g tank and tons of accessories for free!
For fish, I got 30 or so blue danios (sold), 1 Giant Danio, 6 Rummynose Tetras (sold), 3 Rainbow fish (sold), 2 Large Tinfoil Barbs, 2 Red glass barbs (sold), 1 Moonlight Gourami, 1 Weather loach, 1 Buenos Aries Tetra, 2 Tiger barbs (sold), 3 Redfin Tetras

And three of these things! Are they silver dollars or pacu? These look weird for silver dollars but I'm told that's what they are..



Thanks for looking, guys! Please tell me what these are.

They look like silver Dollars to me.

 

[derekp]

they look exactly like my red bellied pacus when i got them a long time ago as babies. thats what i think they are

 

[charles-n-charge]

and a silver arowana too

The thing is, I looked at a friend's silver dollars, and they look way different in color, just really close in shape...maybe mine are just ugly silver dollars? I dunno. Either way, they're pretty cool fish! Just wish I knew for sure what they were.

They don't appear to be Pacu.
And they do look a little different compared to your average Silver Dollar, so this might be a similar species.

Definitely look like fish food for the arowana in a few months.

They Are silver dollars. Theres a bunch of different kind out there.

Definitely look like fish food for the arowana in a few months.

I have a 100 gallon tank that I am moving the arowana into when it gets just a bit bigger. The 65 gallon in these pictures is crowded at the moment but I am cycling another new tank right now for all these tetras and stuff.
