Wow, that really sucks....my buddy had 10 babies and as they got older the one that bullied the other started to eat the others....now he has one....sad story.
not true u can add more of the same size as long as u remove all piranha rearrange the tank and re introduce them at the same time there will not be any established territories they will be fine
Those are juvies and of corse if u dont feed them they will eat eachother but usually not the whoke fish Sorry for your lose man but u can always get another about the same size and they should be fine But make sure u dont miss a feeding or it will probally happen again
i recently had the same thing happen. i have had 4 reds, all are the same size. one day, they just seemed to turn on one and bit and bit and bit until there was not much left of him. i have expected this to happen for the last 2 years i have had these guys, but i was still surprised when it actually did.
so if I wanted to end up with 4 or 5 RBP and I am starting with 3/4" fellas, how many should I invest in? I would say I am an average aquarist always learning and doing my best, but yes...I forget feedings and every once in a while a few extra days slip in between cleanings. would 12 be excessive? Also, at what age and how would you recommend culling to that number if I have more when they are big enough to satisfy my tank requirements?
