I think thats the one! I managed to get a picture, but its not too good... see? The blue eyes aren't as bright as the ones in the picture above mine, but I think its the same one... mine isn't a very good picture; I don't think you can even see the eyes in my crappy pic... but they do have blue
Its also a really big pic, so it will take a bit to load... but heres the URL from a freinds site... mine wouldn't upload it

I got it from my english teacher, and she's had it for about 8-9 years... That may be why its blue eyes are duller than the other professional picture.
And about the shell, its been in there for years, and it hasn't harmed any of the fish yet, but I am still going to take it out. (I have heard that real shells harm freshwater fish)
I will take very special care of it... I'm afraid that it will die soon, since its so old, though. Its in a 50 gallon tank, with other fish, but they are all afraid of it, and leave it alone...

Funny story about its name: My teacher's dad named it Frank after Frank Sinatra, because of its blue eyes :laugh:
Edit- Heres another pic I found of it... and it says that HEALTHY specimens have bright blue eyes, and their eyes are not sunken... so I am thinking that maybe mine is not really in top-condition, so that might be why the eyes are dull
