I have a lot of Aros and have had them for years.

I did not mean all are killers. I have all kinds of aros with other fish.

It is the new additions to the tank that tend to get killed.

And, again, when agressive, the list starts with Jars, followed br greens and RTG's

I totally agree that new additions to the tank are usually the most at risk. My resident green was chasing around (snapping at) bigger blue, red and similar x-back around a large tank (so space was not really an issue).

Hmmm, funny there is a mention of RTG aggressiveness. Now that HBRTG has settled it has beaten it is new green tank mate (not original green) into submission (at the bottom) ... and now there is a contest of will between HBRTG and black (black is losing from what i hear) ... i have never seen an aggression in such puny creatures ... contemplating what to do ....

Back to the original question: death is by being eaten if fits in mouth (see MsMassPoly's new thread) or by "thousand cuts" or through stress

PS: my jar is a whoos - i hope he stays that way - it is a fairly large jar housed with bigger silvers
 
I'd take that black out, Ctoy! No chance on earth that it resists asian agression....stress will kill it

I am gonna go with a divider (temp solution ... i was hoping to beef them up and put in the large com tank) ... i am apprehensive of putting such a small black with larger new asian arrivals + plus the current is much stronger in the big set-up. ... my other small tanks (i still got two) are all not set-up and plus i am not at home but in different province at the moment ....just what i need
 
Jars ram their opponents if there is significant distance, but if it is up close the Jardini uses it's head/body as a whip with it's mouth open attempting to whip and clamp down on its opponent at the same time. If the Jar is able to make solid contact with this action, the opponent usually ends up unconscious or dead from blunt trauma.
 
You'll be surprised how painful jardinis can bite too. I was bitten by my own when I tried to hand out a block of bloodworms. It simply jumped and bit my fingers much to my surprise I bumped my head on another tank.
