  1. Default Murderous Australian rainbow?

    0 Not allowed!
    So I only had one Australian rainbow for a while and he got pretty big, so I got two more for him to school with, they were both much smaller than him. But I came back from college a month after I got the two for him to school with(my boyfriend takes care of them while I'm away) and it turns out the larger one had died. I had seen one of the smaller ones nipping at him but I figured he was three times their size so he could out them in their place. But I am pretty sure one of them murdered him. I out three hatchet fish I'm there the other day (it is a 55 with five Bolivian rams and one high finned pleco along with the two rainbows (who sit in the middle even though they belong at the top) my reasoning was hatchet fish are semi aggressive so if the murderer picked on them they would be able to find him off. So the hatchet fish have done very well, my question is should no get another rainbow? So the other two can school? Because boyfriend thinks that he is aggressive because he isn't in a school. And if I should add one how to into about it so he doesn't murder the newbie?
    Thanks for the advice

    So to sum it up, the larger rainbow was found dead with a smaller one nibbling at it?
    Fish scavenge other dead fish. That is perfectly normal and has little if nothing to do with aggression. The larger rainbow may have died from something unrelated.

    No the larger one was healthy and I out the smaller one in and he beat up on him so badly that I think it may have killed him... I thought the larger one would be able to hold his own but I was wrong

    Rainbows are actually rather aggressive among their own species. I had a group of dwarf neons in a 55, 3m/2f as per the recommended ratio, and they still beat up and killed each other. IME the Australians aren't quite as bad, but you really should have a larger group to distribute the conspecific aggression better.
