piranha ID

  • We are currently upgrading MFK. thanks! -neo
I don't think marginatus has red eyes. rhom of some kind???

what did G label it as? or this is one of his unknow piranhas?
 
My knowledge of Piranha is very limited... since i can't own one legally here.. But i have been reading and researching.....anyways.. doesnt that just look like a Red Belly Piranha?

nope, sorry but that ain't no rbp, serra for sure
 
could be marginatus.

look at the hooked fin could be a tell for what it really is.

dont think its a rhom though, try posting on pfury they have a lot more knowledgeable people on these short of things.

my blue has some nice red/orange on the anal fin and gill plate. guyana rhom also has red/orange on the anal fin and gill plate.
unless marginatus has red eyes, I don't think that's one.

does marginatus get red eyes? G has a larger one there and it doesn't have red eyes. the smaller one got some nice red eyes.

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?
