OK what are your experiances with piranhas?

do you own any?
if so what species?

I have 2 Red Belly Piranhas "P.Nattereri" (which I know is not a good number)
and they live with some neon tetras and zebra danios, I did have a severum with them for the past year, but recently the agression between it and my piranhas was too much so I seperated them.
 
Hi, Innes, and welcome to Aquaria Central. You cannot put pictures in your signature, so that one won't show up...

A little more helpful to those members considering Piranhas would be how large your tank is and whether those fish are merely coexisting until eaten or not.
 
well I wouldn't reccomend anyone was to buy 2 RBPs, I would suggest to keep more than 3 to reduce aggression between them, and also the smallest tank size I would reccomend for RBPs is a 55 gallon (USA) were you could keep up to 5 for life.

as for whether my fish are co-exsisting or not, I have had 3 danios for 5+weeks without losing any and I havn't lost a neon for 4+ weeks


these are new additions to my tank and I did lose a few at first, but that could have been any number of reasons and not nessecarly the piranhas having a midnight snack.

but I also only am using cheap fish just incase my piranhas do eat them.

piranha tankmates are not ofter long-term, however it does sometimes happen.

if you were to want to mix piranhas with other fish you would be best with RBPs as they are the least aggressive and terratorial.
you can also mix the pygo species together - but not serras which must be kept alone (with the exception of S.Geyri)



and I have removed the pic from my sig - why cant I post it?
 
Nobody here can put pictures in their signatures. Forum rules...the bandwidth cost would be a little excessive.

I was not trying to flame you on those tankmates, but I was pretty interested to hear that they've been making it for so long...P's have a pretty bad reputation, as you've probably figured out!

You must be keeping them well-fed--what is your feeding regimen?
 
well to be honest I just feed them when I remember - this is sometimes days apart, but sometimes every day.


and sometimes the piranhas dont even look interested in the food provided, and my severum used to often eat the lot.


Piranhas are just really misunderstood by most people, and especially by fishkeepers who have not had experiance of them.

I guess their reputation is a little over the top, and this could be as many piranha owners want to boast the meanest or most aggressive fish ever!!!!
when in reality it could be taken down by a flowerhorn or a fakata puffer or something like that
 
here's a post from ScottomacD and I couldn't have said it better myself. This comes from the "meanest fish"thread


"My 2 cents.

The pirahna aggressiveness level has to be one of the most overrated things in aquaria history.

They are pack hunters in the wild and that and only that makes them a danger. No single pirahna will would ever even think of attacking any fish, man, woman, animal etc. that was the same size or bigger. This is a known fact. Yes there are the stories of the fish that goes bonkers then kills and eats a man or cow or whatever by itself. Those are the rarities of life.

I have owned and watched a 6 inch Salvini kill and eat a 11 inch domiant male Texas. In the texas' own tank. Dosen't mean all salvini's are killers. This one just happen to be one special SOB with a serious chip on his perverbial shoulder

I have seen many adult pirahna in tanks my life and not ONE has EVER come up to the glass and challenged me to protect it's terrotory or try and attack or eat me. I am talking about both tank raised and wild. Established or new to the tank. They have turned tail and hid, but never challenged. A true aggressive fish will. Be it african or SA/CA.

All of the fish mentioned so far could (except the previously mention pirahna) fall under the most aggressive fish area. Depends on the fish though. They all have their own personalities."
 
When you think of the fact that they were evolved from fin-nippers, Piranhas, as ambush predators who're just hungry, aren't that aggressive.

Thanks for sharing the info, Innes!
 
My cousin had 8 RBP. He got them when they were babies, 3inch long...

he didn't feed them for 4 days and they were going after the smallest piranha.

One water changed killed them all. :(
He bought a Koi as a treat and they ripped that fish apart in 2 mins.

He introduced them with other fishes and they didn't bother the other once as long as they were fed. But when he didn't feed them for a while they killed everything in the tank.
