Welcome to the forum....

Here is what I would do. (Austin, I hope you read this)

Find a web site that is reputable and has keelback pictures and data, print it out and take it to the store.

On a slightly twisted variation to all this, Our local petco has none, I keep checking.

I want one of these Keelbacks!

However PETCO has problems, and is misleading the public, not a first for them.
