I have had the same Silver Dollar now for 5 yrs,i bought/rescued him from wal-mart,he was dime size and in a tank full of Oscars(same size) getting his butt whipped.He is now close to 5 inches maybe even larger,and has had an assortment of tankmates but always seems to survive,i have no plans of getting rid of him until the good Lord decides its time for him to go.
Had a Jag for 6 years, the recurring theme of being away and there was a power outage...... Oh he was the meaniest friggin fish I eve owned, but still loved the dude, his final resting place has been in my freezer for 7 years....
