Hi everyone-
I just read in the fish profiles (very informative, by the way!!!

) that silver dollars do better in small schools or they get easily scared...I see that behavior in the silver dollar I normally have in a 55 gal tank with my young albino oscar, but now is there with only the bristlenose pleco, as the oscar is in a quarantine tank. Even alone, he spends most of the time hiding in a plant and doesn't appear to eat much. Should I get 1-2 more silver dollars for him, or do they need to be purchased at the same time to successfully form a school? I appreciate any ideas anyone has!!
Thanks,
Lisa
