piranha ID

[Diogenes]

I'm no expert, but pigmentation is usually the last thing you consider when you try to ID serras because it can vary so much based on genes, diet, water conditions, light levels, etc. I tried to research this guy last night and I still can't figure out what it is. I don't think its S. marginatus. The hook on the anal fin is just a hook, it's not a full on extension of the 3rd & 4th rays. Also it's only on the anal fins, margs grow extensions on the dorsal and anal fins. Body shape isn't typical of a marg. Caudal fin pattern is not typical of a marg. Marg's have a caudal fin pattern that begins with a broad dark V and then ends in hyaline tissue, this fish has hyaline tissue ending in a terminal black band. Head and jaw are hard to make out because of the angle of shot, but it certainly looks more like a rhom profile than a marg profile to me. Also margs are members of the compressus group which means they have the red-ish eyes, not the actual red eye caused by blood flow through translucent tissues in the eyes.

1) S. rhombeus CF I think it's most likely a CF form of rhom. It's much more likely for a rhom to have orange fins, than for a marg to have red eyes. The body shape is indicative of S. rhombeus. Maybe it acquired some hybrid gene alleles somewhere in the family tree causing it manifest this interesting phenotype.

2) S. altispinis - It's a bit of a stretch but it looks a lot like an altispinis. I can't really get any more specific than that because I haven't seen enough altispinis to know exactly what to look for. I do know that essentially you can't really tell them apart from rhoms without counting rays and proportions except they are more brightly colored.

Here's one pic:

3) S. spilopleura- I know it hardly looks like a spilo at all, but the caudal fin pattern looks exactly like a spilo. Body shape kind of does too. That's the full extent of the resemblance.

Those are my best guesses anyway. Bottom line, it's a cool looking sera. If you like it buy it. Who cares about the latin name after it?

^^^ could be S. sanchezi too. Can't make out the scutes.

some dude on p-fury said sanchezi for sure, but i dont know i emailed george will see i guess, but now im leaning sanchezi too

based on what? color of life? Sanchezi is easy to ID/rule out if you can photograph the serrae.

that fish is in a tank thats all the way on the top of other tanks. I think the pic he posted is probably the best pic one can get.

I'd like to see what George labeled it. I'd be really surprised if those guys got one wrong.

just don't try to sneak em out in your underwear....

Not sure maybe marginatus, what do you think

I think there's a good chance it's a sanch. Check out the curve of the body. It would explain the red eyes, body shape, red fins, and the black terminal band on the caudal fin. It's an interesting color of life for a sanch that big. When you go back, see if you can get an idea what size it is TL, and get a good snap of the scutes.

One things for sure, you've got a good eye for spotting oddballs...

I don't know what you guys are thinking? Its obvious that its red hook silver dollar.
