This is a little bit of true life from my personal website;
My brothers Jaguars had babies a couple of months ago and as is usually the case there was a runt in the litter, but no matter what, he always seemed to find the strength to survive and carry on.
I managed to get him to about two inches and decided to put him in my main tank, bad idea, he had only been in there two weeks when i noticed he was spending alot of time in the top corner.
On closer inspection i realised he was looking a bit tatty, dorsal fin split, tail fin ragged, scales missing here and there basically i had given up on the idea that he would survive.
Anyway having nowhere else to put him, i decided to put this poor sorry speimen into my pirahna tank, thinking that he would be eaten.
More fool me,
even though he was half the size of the four red-bellied pirahnas, he had the sense to back himself into the corner behind the Powerhead. 
Everytime they came near he came back at them all guns blazing. I went back to work the next morning and all I could think about all day was, I will get home tonight and the little fella will be no more, he would have succumed to the vicous Pirahnas.
He has been in the tank for the last five months now and as become friends with the pirahnas and swims quite happily with the group.
