don't know anything about them but... if the anal fin isn't as pointed can it be a female Marginatus?

no, piranhas are not sexually dimorphic. Nice idea though

thanks but I think you'd be wrong. That fish is a Serrasalmus compressus, and this thread is now a zombie back from the dead to haunt the land of the living.

i have never received a single update on darwin, and davey has never posted a thread. I fear the worst. He's probably confined to a 10g at riverdale pets. Kind of makes me regret ever getting rid of him, but I waited until I found a hobbyist who at least ostensibly cared about keeping him.
