I dont know much about Pirahnas, but am slowly learning.
Id love to get 1 for myslef and try taking it, although i dont know which 1 to choose...I was thinking of the SERRASALMUS BRANDTii

Any suggestions

?

Get a Serrasalmus Rhombeus if your only looking one piranha. If you want a shoal of them get six Caribe. A 100 gallon for a Serrasalmus Brandtii is more than needed and you would just be wasting room. But it's up to you. I imagine if you did put a Serrasalmus Brandtii in there it would grow nice and big because it would have more room to swim in. Probably could grow over it's max size because they only need about 40 gallons per Brandtii but they can't be kept together. They would kill each other.

Here are two pictures of Serrasalmus Rhombeus

This is a younger one

This is an older one

I'd get a 12+ Serrasalmus Rhombeus!

id get caribe or natts (red bellys) or its been very popular to mix pygocentrus species lately.

You guys, I think, are misunderstanding him. He is refering to 100 LITRE tank. I dont really know how many gallons that is. But its not 100 gallons

1 gallon=3.8785 liter i think but im not sure on the last number

if it is a 100ltr it will be @ 40 us gal so getting a serra will probably be best and as he asked for only 1 piranha then a brandti would be a good choice or a smallish rhom say 5-6'' .
if it is a 100 gal then i would go with pygo's either reds or cariba but if moneys not tight then piraya @ 6-7

i would say get a rhom

 

[piranha 13]

Well if it's 40 gallons then a Rhom would last in there for a long time or a Brandtii would be perfect for it. Gold Spilos are also aggressive fish that could live in a 40 gallon for it's life.

 

[DiXoN]

sorry it is not a 40 us gal it is a 25 us gal and probably only a 2'' tank i would go with something else than piranha unless you are willing to upgrade

Yea if it's a 25 U.S. gallon than you will need a larger tank. No piranha can live in there for life comfortbly. A Rhom could live in there for a while but you will need to upgrade eventually.

Umm 25g...i'd say 1 Spilo!

 

[thePACK]

a shoal of cariba or ternitzi

can't go wrong

I have an 8" Rhom in a 20 gal. Not the greatest space for him, but its working for the time being..
