What is the smallest silver dollar type fish?

  • We are currently upgrading MFK. thanks! -neo
Are they safe to keep with smaller fish like rummynose?

I've got a group of 5 spotted SD in my main tank, for the most part they are non aggressive when it comes to smaller tank mates. I will tell you though, that I've seen 2 of my larger SD's snag themselves a feeder (rosy minnow) from time to time when I'm giving my cichlids a treat.
 
Thanks, I have six in my 450. I believe the reputation for skittishness they have is due to people keeping them in smaller tanks

I had five red hooks in my 220 and they wreaked havoc every time I walked by, trying to get behind decor or heaters! Smaller than your tank, I admit.
