I posted this as a reply to another thread, but I really wanted to make a thread out of it so I can be sure that everyone has a chance to talk about the behavior I have noticed in my tank.
Tank: 100 Gallon Amazon Setup
Primary Fish: Elongatus Piranha - 5''
Tank Mates: 12 Guppies, some feeder some fancy
2 Neon Tetras
2 Glow Light Tetras
1 Alage Eater ( common, not a pleco )
And 1 very unlucky Feeder Goldfish
---------------------------
Well, aside from the fact that my elongatus is apparently different from most, seeing as I can have a dozen guppies swimming around just fine for the past few months with nothing happening to ONE. I also decided to try putting a few other cheap fish in as trials, long finned zebra Dinos was the lastest I added, and once again, the Elongatus is noting paying them a bit of attention, I also have some neon tetras ( 2 ) , and some Glow Light Tetras ( 2 ), and a common Alage Eater in there. All of these other fish have had no problems mixing with my elong, and it's very shocking and very very very odd, as Elongs have the rep. of being VERY intolerant to tank mates. So I guess it "CAN" happen, just reguardless of a species reputation they are subject to having their own personalities. While I am certainly aware that one day my Elong may just go on a killing rampage and all will be corrected, But as for now, he doesn't really seem to care about anything that he could eat in one bite. I find that observing that other fish activities while being in a tank with a piranha is kinda.... "neat". For example... When I put in a feeder goldfish ( which I am about to stop doing before too long ) the guppies will actually school together and attack the goldfish kinda trying to corner him with the piranha, being as they will feast off the remains after the piranha has his fill. And it's a pattern with them, they corner the goldfish in with the piranha, and will literally hold the goldfish there for long periods of time. It's very odd to sit and watch. I'm going to make a new thread with this observation as well to get other peoples thoughts
