Can 12 Chromis be introduced at the same time into a 190g?

meaning one became dominant, then killed the others, and then turned on himself.

So I know that there is a strong chance that one can become dominant and kill off others. But are you joking when saying it can turn on himself because of a reflection? Does this happen to many other species as well?

Yup most fish species if they see an image of itself can attack as they perceive it as a threat to their dominance so will attack their own image

To the point of death?
Can you post a link to this info please.

Yes, I have seen other animals like kittens do it and birds. I just did not think it would be a fight to the death.

This may pose an issue in my tank. I have a penninsula and can see the fish seeing themselves in the end of the tank when the light conditions at certain times of the day, create a mirror for them...
Who would have thunk...man, learn something new everyday. Only been doing this for a year and something as simple as that, I did not know. I will have to do more research...geesh...

While it is known they can attack their own image I have not heard of any fish fighting to the death with themselves although I have read that they can exhaust themselves to the point where they can become targets themselves leading to possible injury and possible death from said injury

Well sometimes it's just best to share actual experience rather than just what you have read. Lots of that stuff that you read is usually just what some self proclaimed expert which is usually a newbie has posted. I'm by no means an expert at all but I may be what Brad edited our of one of my posts haha

That is very true Bill but I am sort of a nut when it comes to researching and I generally try to confirm from multiple sources about subjects I generally don't take information from one source and spout it off as truth I look it up in several locations from various authors and make an informed choice.

And as we know the internet never ever lies

What?

I've had dogs and cats that do the same thing.


When you think about it, in the wild, in the ocean, you just don't have the opportunity to see your reflection all that often.

It would probably freak me out too if I had never seen or heard of a mirror before.
