Is this a redhook?? true redhook?

[Cichla dude]

I was given this as a redhook from someone on craigslist. It looks like myleus schomburgki without the black bar. I was thinking it could be a young redhook, but the young ones I've seen before have the whole hook.
Here are some pics for you to decide:
(if you can provide pics of small redhooks that will help too.)

Looks like a regular 'ol SD that you see a the big box stores to me.
I could be wrong though.

nah he has a more elongated jaw... he has the redhook looks just a shorter orange hook.

true redhooks develop the hook at a pretty young age, usually by the time they are 2" long, im sorry to say that yours is not a true redhook (Myleus rubripinnis)

nah he doesn't have the sd shape he has the redhook shape.. can he be nipped?? maybe

remember that there are several species of silver dollar, ours doesn't look like you everyday run of the mill redfin metynnis, but it also does not look like any of the myleus species i am aware of
