Seek some advice from piranhas keepers here as I have not seen any other types besides the usual RBP.


Saw an interesting species at my LFS. Understand it should be a Rhombus but any idea which type it is?

Would like to add the fish is about 4-5 inches and came from Columbia. :)

Will be scouring this forum for more information on this fish as I had placed a booking for it and will be keeping it as a single fish in tank.
 
The color variants are almost impossible to tell until the fish gets older, and honestly are made up by vendors to make money. The guys mentioned can probably tell you which rivers/locals tend to have higher quantity of the variants. The biggest difference between the "diamonds" and non-diamonds are as follows:
- Diamonds tend to stay smaller. There are a couple 11-12in ones out there, but you will never see a 17in one
- I have heard diamonds tend to be more aggressive, but this is almost impossible to prove
- Some folks claim that diamonds are less susceptible to hith has large rhom get hith easily. I personally don't really believe this

Definitely looks to be a rhom, a closer look at the scutes would confirm.
However, like said before, it's very difficult to identify at this length/age (diamond or not).
I'm sure someone else here would be able to provide an accurate representation..

Thanks for all the replies. Much appreciated.

In the middle of setting up a new tank for this guy; I read that darker background and substrate will bring out rhom best colors. Black sticker and red sand?

Will be bagging this fella home in a couple of days and update with better pictures. :)

Besides Rhom, any idea what could it be? Reason is I had prepared a 3 footer (50 gal) grow out tank with an Eheim 600 for him - understand rhom takes ages to grow.

So long that it is something that won't outgrow the tank in 6 months to a year will be good.
