As mentioned in another thread, I've got 5 of these little guys in my tank, picked up from the local lake. Can't get a good pic of them, they just don't stop moving when they see me (always expecting food).
No clue as to what species they are yet, too young for me to tell. Any guesses? Bluegill? Longears? Redears? etc? They're only 3-4" right now, and they have a slight blue tint to their fins.

Here's a video of them being fed.

Longear sunfish.
 
Why is that? They seem like dollars too. What is the giveaway? (Ear tab being long doesn't count. Lol)

I agree with you, never seen a Dollar in person but looking at Google images, they look like Dollars more than Longs.
 
One time, Dollar and Longear were once thought same species. Some subspecies of Longear do not have long ears. My northern longears looks similar to these sunfish in question.
 
What do you mean no differences? Clearly there is.
There isn't any differences between a longear and a dollar. As I said this before, Dollars were once thought they are same species of Longear before they were recognized as a separated species. It is not uncommon for a fish biologist mistook a dollar for a longear or a longear for a dollar where both species overlaps. The only way to tell the difference between them were based on the region where the dollar sunfish were found. SC do not have any native longears.

But here's my question for you: what is difference between the longear and the dollar sunfish?
