Are my Silver Dollars all right?

[archosman]

My goal is to get a 55 or 75 gallon tank so they have a little room to run around in. They're very skittish. I also have 2 dwarf gourami in there as well. It took forever for the tank to cycle.


I could swear I read somewhere online that they may actually be in the family of Piranha. These are vegetarians though. I did read that I can pretty much forget about having any live plants in with them as they will demolish them. Here's a pic of the tank...

And the big fella. Looks a little Piranha-ish... but he's a fraidy cat when I turn on the lights. The gourami come to the surface everytime I open up the top. They know where the food's coming from.

That's what my silver dollars look like, minus the red dot. (I mean the spotted guys)

I need to get me some of those then! They're COOL!

Look like RBP's, wonder why you would want them A.....

but those are definetly SDs, not RBPs....SDs are characins and come from family serrasalmidae too just like piranhas so a lottt of people mislabel SDs as Ps....They are pretty much the closest thing to being a piranha. Cool fish though, but there are just too many characteristics that set them apart...to me anyway
