this is Olive - my young Oscar. Over the past few weeks, the predominant "O" spot at the base of the tail has transformed into a perfect heart....

my little tiger has a perfect 0, i hope it stays with him
healthy looking fish u have, is he your only oscar?

Cool, so the o spot is actually changing over time?
When i look very closely mine is developing a tiny spot, on one side of his tail.
I hope it gets bigger.
I'd settle for a heart shape...

yes, the O spot has definitely changed over time. I've had the fish since October (when it was a wee 2" or so). For the first month, there really wasn't much of a spot - just a bit of a greenish spot - hence, the name "Olive" - my other Oscar that I got at the same time didn't have the spot; and that is how I told them apart.

over time, the spot has been getting more predominant, and I'd say over the past month has really turned into a heart. I hope it's done transforming and stays this way!

When i went to get my O i recognized him by his attitude and the white edges on his fins.
When i finally bought him and got home i noticed that he didn't have a O spot.
Most of his siblings had the spot.
My next O will be a Tiger with an O spot!
In Holland the Oscar is called Peacock bass. (just like the cicla monoculus)
When people ask me why my fish is called a peacock, i say, he's supposed to have a starry eye...

Haha...thats very cool! Very nice looking O you have there!

heres my 2 babies with their spots...

You can now see how a predator could mistake the Oscars tail for the head, thus saving the Oscars life in the event of an attack.
