looks marginatus, never seen spotting on a 6'' rhom never and i had them all, unless he's smaller and i cant tell, but his eyes are red might be rhom though
The true serrasalmus rhombeus is limited to Guyana. It is an amazing species of piranha and it is a very large species. The only way to really know if it is a true serrasalmus rhombeus is if you do a DNA test on it, Lol. I was only joking about that, but it is true. The maximum size is 18" according to South American locals and in the aquariums they can reach a size of 12" and above. Now if your talking giants, you can find them in the wild as large as 18"+ (very rare). This species of piranha is my favorite piranha and they are very interesting to raise. Good luck.Diogenes;2997698; said:I thought that it might be a good idea to post up some descriptions and ways of telling apart the different color morphs of S. rhombeus. I for one think a rhom is a rhom is a rhom, but I'd like to know how to tell them apart. So I'm gonna post up some "types" of rhoms and some pics, and I'm hoping you guys will chime in with some good info on the various types of rhoms.
We're looking for how much they cost, how rare they are, where they come from, and how to tell them apart from one another. I'll do the first one and maybe somebody else can post up the second one.
Here we go:
My personal favorite color of rhom is the jet black high back. They don't seem quite as popular as the diamond rhoms, but I think they look downright nasty, and to me thats a good thing.
Jet Black High Back:
Price: I found this listing on AS. It's a 12" and it's listed at $500 bucks.
Country of origin: Peru
How to identify: The jet black high back is extremely dark in color. These rhoms are truly deserving of the common name "black piranha." Also they appear to be more laterally compressed than some other rhom variants, with an extremely "tall" back, which gives the fish an almost disc like over all shape. All rhoms have red eyes.
Rarity (common, uncommon, rare, very rare,): rare
I hope somebody will write a profile like this for the other variants. Blue diamond anyone?

as far as I know, rhoms are found in Bolivia, Brazil, Columbia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. There are many ways to ID rhoms besides DNA. Matter o' fact, there are a number of members here and on other forums that can ID rhoms in their sleep. Might want to reconsider this statement, and do a little more research.
