Please identify this fish...

Shape of the head does kind of look like a compressus, however the terminal band on the tail isn't dark enough.
I'm going to say rhombeus also.

sorry for OT, but can you link me to a larger version of your avatar? that piranha is awesome!

@ topic: i don't think rhoms have red bellies, so i'd say it's a compressus, but then again i'm certainly no expert
just let it grow, once it's adult you will know if it's a rhom or not
