silver dollars

[mostanks]

i have one
1=Metynnis argenteus(reg silver dollar)

1=red hook

and 2 that look like this one,but the lfs had them labeled as "roosvelti"spelling

i don't know much bout silver dollars except that they make great dithers/targets,the problem is my green terror and carpenti always pick on the red hook(the biggest sd i have )he's bigger than the carpenti-which is the one that is doing most of the damage.
i don't know what to do i mean i got it as a target/dither but i didn't think they'd lock in on him alone-oh and my exodon tetras are pickin on him too.

well the silver doller is what i would call a semi agressive fish but most silver dollers are peacful and the green terrior bulling it is common bad match up of fish that is about all i can tell you

I agree! Definately a bad match of fish. I have 2x Angel fish and they sometimes bully my silver dollar if it gets too close. I have never seen my sd harass anything except my bloody plants!
