Most active Serrasalmus?

[piranha45]

What specie(s) of serrasalmus do you think are the most active, in terms of swimming around regularly, user interaction, etc.?

Also, what's the fastest-growing serrasalmus species?

S. elongatus, I've only seen them kept once, in A very large a tank in Germany. They don't get as big as some, about 12" max. But they are faster than a choir boy at a bishop's convention and almost as jumpy. I never owned one but I would love a small school.

hehehe, great analogy.

i would have to say the Spilo is most active in my experience with serras.

 

[piranha45]

elongatus would be a close 2nd, right?

i have kept quite a few serra species: elongatus, rhom, sanchezi, irritan, mac. my 7" rhom currently is the most active and outgoing. first piranha i have owned to chase a finger like a cichlid. the mac was a close second. my elong sucked.

From what I've heard, rhoms are kind of a grab-bag in terms of activity.

The most active Serrasalmus I've owned was an irritan.

I don't think there can be a sure way of evaluating the activity level of piranhas, however, there should be like the top 5 or something (not in any particular order that is).

For me it was my manny- By far more active than my rhom.

how big did your manny get to? what happened to him?
