Well I saw one of my babies the other day, atacking others food and trying to catch from others mouths, well all of them swim on their own food...but no incidents till today.

Lucky I was around!.... I saw one baby eating another one... I mean not the tail, not a small piece, she had almost half of the other baby inside her, she didn't mind the size (not as big but very close)...so I tap the head and grab them...for my luck the other was still alive.

So I put the agressive one in a bowl, not a sign of eating, then I tried worms...the moment she saw movement that was the end of the worm, she attack very agressively, could be a explanation or it's just nature?
