I can't vote. I wish you had the word shoal there. My favorite thing about piranhas is the shoal chowing down on big fish or animals. It doesn't matter if its a ternetzi or a redbelly shoal to me its the same. Piranhas in a frenzi is about the greatest pack eating animal I have ever seen.
I would like to have a shoal of either monster rhombeus/ternetzi/piraya. I have one monster rhombeus. If I could find maybe 4 more his size or larger, I will definately set up my big tank to accomodate all of them
I had a white rhomb well I think it was a *****, but anyways I had to get rid of it. The fish would not even let me clean the tank, If I stuck the gravel sucker in there he'd try to kill it, lol well kinda like the snake head I got now lol.
I voted RBP thats only because they make a great shoaling and interacting P that is still aggresive. To be able to cope with each other and to be nasty to so many other is just a miracle of nature:angry:
